Answer:
Concave up: (0, infinity)Concave down: (-infinity, 0)a. The graph is concave up in the interval 0 ≤ x ≤ +∞
b. The graph is concave down in the interval -∞ ≤ x ≤ 0
To answer the question, we need to know what intervals are
What are intervals?Intervals are range of values in which a function is valid. It can either be the range of values of input or output of the function.
a. Interval where the graph is concave upFrom the graph, we see that the function is concave up in the interval 0 ≤ x ≤ +∞
So, the graph is concave up in the interval 0 ≤ x ≤ +∞
b. Interval where the graph is concave down
From the graph, we see that the function is concave down in the interval -∞ ≤ x ≤ 0
So, the graph is concave down in the interval -∞ ≤ x ≤ 0

The correct statements regarding the linear function are given as follows:
The slope is 1/2.The y-intercept is -4.The points (–2, –5) and (8, 0) are also on the line.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the line goes through points (-6,-7) and (8,0), hence the slope is given by:
[tex]m = \frac{0 - (-7)}{8 - (-6)} = \frac{7}{14} = \frac{1}{2} = 0.5[/tex]
Hence:
y = 0.5x + b
When x = 8, y = 0, hence the y-intercept is given as follows:
0 = 0.5(8) + b
b = -4.
When x = -2, we have that:
y = 0.5(-2) - 4 = -1 - 4 = -5.

There are several ways you can find the values of an exponential function for different values of the independent variable. You can read them from its graph, evaluate the formula, or recognize the relationship between the values.
P(t) for different tThe graph shows you the population is 10 in year 1, up by a factor of 2 from the population of 5 in year 0. The exponential nature of the function means the population will double in each of the next few years:
2 years: 2 × 10 = 20

how to convert 798 in the base of 2
Subtract the largest power of 2 from 798 such that the difference is not negative.
2⁹ = 512 and 2¹⁰ = 1024, so the largest power of 2 smaller than 798 is 2⁹, and
798 = 512 + 286 = 2⁹ + 286
Repeat this process with the remainder, 286.
2⁸ = 256, so
286 = 256 + 30 = 2⁸ + 30
⇒ 798 = 2⁹ + 2⁸ + 30
2⁴ = 16 and 2⁵ = 32, so
30 = 16 + 14 = 2⁴ + 14
⇒ 798 = 2⁹ + 2⁸ + 2⁴ + 14
2³ = 8, so
14 = 8 + 6 = 2³ + 6
⇒ 798 = 2⁹ + 2⁸ + 2⁴ + 2³ + 6
2² = 4, so
6 = 4 + 2 = 2² + 2¹
⇒ 798 = 2⁹ + 2⁸ + 2⁴ + 2³ + 2² + 2¹
or more completely,
798 = 1×2⁹ + 1×2⁸ + 0×2⁷ + 0×2⁶ + 0×2⁵ + 1×2⁴ + 1×2³ + 1×2² + 1×2¹ + 0×2⁰
Then the base-2 representation of 798 is

when the car is 9 years old?
The value of this car when it is 9 years old is equal to $16,757.00.
How to calculate the value?In order to determine the value of this car when it is 9 years old, we would use an exponential function which also relates to compound interest as follows:
A = P(1 - r)^t
Substituting the given parameters into the formula, we have;
A = 32,200(1 - 0.07)^9
A = 32,200(0.93)^9
A = 32,200 × 0.5204

How to solve equalities?We are given the equality;
2 divided by 9 = 5/2 divided by 5/4
We want to check whether the left hand side of the equality is equal to the right hand side. Thus;
Left hand side can be expressed as;
2 divided by 9 = 2/9
Now, right hand side can be expressed as;

Answer:
a = 8
b = -2
c = 12
Step-by-step explanation:
a + a + b = 14
2a + b = 14 ⇒ ( 1 )
b + b + c = 8
2b + c = 8 ⇒ ( 2 )
a + b + c = 18 ⇒ ( 3 )
First, let us make a as the subject in equation 1.
2a + b = 14
2a = 14 - b
[tex]a=\frac{14-b}{2} \\a = 7-\frac{b}{2}[/tex] ⇒ ( 4 )
Let us make c as the subject in equation 2.
2b + c = 8
c = 8 - 2b ⇒ ( 5 )
Now it is clear for us that, we can replace a & c with ( 7 - b / 2 ) & ( 8 - 2b ) respectively.
And now let us solve the equation 3 to find the value of b.

[tex]2a+b=14\\\\2a-2=14\\\\2a = 14+2\\\\2a=16\\\\a=8[/tex]
Now, let us find the value of c.
