The arrows indicate that the graph of the function continues beyond what can be seen in the image.
Notice that the graph does not appear to have asymptotes; then, the domain of the function is:
[tex]\text{domain}=(-\infty,\infty)[/tex]And the range is:
[tex]\text{range}=(-\infty,\infty)[/tex]Since the graph seems to continue towards the +y-direction and the -y-direction
Finally, notice that for each value of x, the graph has only one value of y. This is the key characteristic of a function; the graph is a function.

Real world compositionsWhat is the volume of a spherical balloon after 11 seconds if the radius of the balloon is increasing at 1.3 cm/sec? Round to the nearest tenth of a centimeter solve using composite functions
Answers
In this case we have two functions. The first one is the volume of the balloon and the other is the value of the radius. Both functions depend on the variable time.
Finding the functions to solve the problem, we have:
[tex]\begin{gathered} V(t)=\frac{4}{3}\pi r^3\text{ }^{}\text{ (First function)} \\ r(t)=1.3\cdot t\text{(Second function. Let us suppose that the initial radius is equal to zero)} \end{gathered}[/tex]Let us replace the second function in the first one to get a composite function. Doing so, we have:
[tex]\begin{gathered} V(t)=\frac{4}{3}\pi(1.3\cdot t)^3 \\ V(t)=\frac{4}{3}\pi(2.197\cdot t^3)\text{ (Raising the expression within parentheses to the power of 3)} \\ V(t)=2.93\pi\cdot t^3(^{}\text{ Multiplying constant terms)} \end{gathered}[/tex]Now, we can replace t=11 to find the value of the volume.
[tex]\begin{gathered} V(11)=2.93\pi\cdot(11)^3\text{ } \\ V(11)=2.93\pi(1331)\text{ (Raising 11 to the power of 3)} \\ V(11)=12248.88\text{ (Multiplying)} \end{gathered}[/tex]The answer is 12248.9 cm3 (Rounding to the nearest tenth of a centimeter).

What is Inequality?An order relationship with greater than, greater than or equal to, less than, or less than or equal to between two algebraic expressions.
The given inequality is
-3x+4≥10.
To solve the above inequality
Subtract -4 from both sides.
-3x+4-4≥10-4
+4 and -4 we get zero.
-3x≥6
Divide by 3 on both sides
-x≥2
When negative sign is multiplied on both sides, the greater than or equal to symbol changes to lesser than or equal to.

What is the slope of a line perpendicular to the line whose equation is 6x+8y=−128. Fully simplify your answer.
Answers
The slope of a line perpendicular to the line 6x + 8y = -128 is 4/3.
Given,
The equation of a line = 6x + 8y = -128
We have to convert this into standard form of linear equation, y = mx + b :
So,
6x + 8y = -128
Add -6x to both sides,
6x + 8y - 6x = -6x - 128
Now,
8y = -6x - 128
Divide 8 on both sides
8y/8 = (-6x - 128) / 8
We get,
y = -6/8x - 16
Here, this is in standard form of linear equation.
Here slope of line, m₁ = -6/8
We have to find the slope of line(m₂) which is perpendicular to the given line.
If the line is perpendicular, the slope(m₂) will be the negative reciprocal of the slope(m₁) of the given line.
That is,
Slope of line, (m₂)= -(m₁) = - (-8/6) = 8/6 = 4/3

The triangles are congruent if two sides and the included angle of one triangle are equivalent to two sides and the included angle of another triangle.
In this case, the length of side FE is 40 and the length of side IH is 20. This gives a value of 60. Therefore, J should measure 60°.

a casting weighted 148 lb out of the mold. it weighed 141 lb after finishing. what percent of the weight was lost in the finishing?
Answers
The amount of weight lost will be equal to 4.72%.
Percentage may be defined as a form of expressing a number as a fraction of hundred. To find the percentage of a number we divide the number by the total amount and then multiply the answer with hundred. The initial weight of the casting was 148 lb and the final weight is 141 lb. To find the percentage we use the formula
Percentage lost = [(Final weight - Initial weight)/Initial weight] × 100
Percentage lost = [(141 - 148)/148] × 100
Percentage lost = ( -7/148) × 100
Percentage lost = -0.0472 × 100
Percentage lost = -4.72% and since we write the absolute value therefore, Percentage lost = 4.72%.

............ minutes per day
Answers
The slowest rate of change that is the slowest for the training program is: 3 minutes per day.
What is the Rate of Change of a Function?In a given function that is expressed in slope-intercept form as .f(x) = mx + b, the rate of change of the function is represented as "m", while the starting or initial value is represented as "b" in the equation.
Given that Rachel increases the time she runs by 3 minutes for each day, then, the rate of change per day for the training program or Rachel is 3.
Given that the function .f(x) = 5x + 30 represents the minutes Nicole runs per day in the training program, then the rate of change is represented as "5" in the equation. This means that each day, Nicole increases her time of running by 5 minutes as compared to 3 minutes per day that Rachel increases her daily runs.
3 minutes per day is slower than 5 minutes per day, in order words, the slowest rate of change is therefore: 3 minutes per day.
