Answer:
Recall that the domain of a function is the set of input or x -values for which the function is defined, while the range is the set of all the output or y -values that the function takes. A simple exponential function like f ( x) = 2 x has as its domain the whole real line.

quadratic form to vertex form with a vertex of (-4,-1) and a y-intercept of 7
Answers
y = a(x - h)^2 + k
Where:
vertex = (h, k)
Axis of symmetry: x = h
The value of “a” determines whether the graph opens up or down, and makes the parent function wider or narrower.
The value of “h” determines how far left or right the parent function is translated.
The value of “k” determines how far up or down the parent function is translated.
Now that we have these definitions, we can substitute the given values into the vertex form to solve for “a”:
Use vertex = (-4, -1) and y-intercept, (0, 7):
7 = a(0+ 4)^2 - 1
7 = a(4)^2 - 1
7 = a(16) - 1
Add 1 to both sides:
7 + 1 = a(16) - 1 + 1
8 = 16a
Divide both sides by 16 to solve for “a”:
8/16 = 16a/16
1/2 = a
Since a = 1/2 (which is positive, implying that the parabola opens upward), and the vertex occurs at point (-4, -1) as the minimum point:
The quadratic equation in vertex form is:
y = 1/2(x + 4)^2 - 1

On the first day of a family road trip, Kai's family travels 365 miles.
On the third day, they travel 20% farther.
How many miles does Kai's family travel on the third day?
Answers
The number of miles traveled by Kai's family as required in the task content is; 73 miles.
How many miles was travelled on the third day?It follows from the task content that the number of miles traveled by Kai's family on the third day is to be determined.
On this note, since the family travelled 365 miles on the first day and travelled 20% farther on the third day;
The number of miles traveled on the third day can be modelled as;
= 20% of 365
= (20 / 100) × 365
= 73 miles.
On this note, the number of miles traveled on the third day is; 73 miles.

Line R passing through point P(-2, -1) and point (3,5). Find the slope of line R.
Answers
Answer:
Slope: 6/5
Step-by-step explanation:
For this problem, you'll need to apply the slope formula Y2-Y1
X2-X1.
Let's now assign each number their position in the formula. The first set of parentheses, (-2,-1) is going to translate to (x1,y1). (3,5) will translate to (x2,y2). Now, when you put it all together, you get 5-(-1) / 3-(-2). This would give you 6/5. That would be your slope. You can then proceed to graph it. Hope this helped! :))

Is x = -2 a function?
Answers
Answer:
yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
If you graph this function, you'll find that it looks like a vertical line, straight up and down. In a function, each x-value has to have exactly one y-value. In this function, however, any y-value you plug in gives you the same x-value: -2.
The one x-value, -2, has an infinite number of corresponding y-values, so this is definitely not a function.

Multiply
(x - 1)(x^2 + 5ix - 5ix + 25) *Remember that i multiplied by i equals negative and in this situation, one of the variables was already negative, so negative multiplied by negative is positive*
(x - 1)(x^2 + 25)
