On the graph shown, what is f(-2)?
a. -2
b. -1
c. 2
d. 3

option D

Step-by-step explanation:

we know that

In the graph there are three functions

the first function for the interval----------->

the second function for the interval----------->

the third function for the interval----------->

represent the value of the function for

so

The value of is included in the interval of the first function

therefore

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
