1. if f(x) = |x + 6|, find f(−10).
a. -16
b. 16
c. -4
d. 4
2. if f(x) = |x − 4| + 5, find f(1).
a. 8
b. 2
c. 0
d. 10
3. if f(x) = 8 − 3|x + 2|, find f(−6).
a. 20
b. -16
c. -4
d. 4

What you need to do just plug the number into the x values in the function. 

1. f(x) = x + 6 
f(-10) = -10 + 6 = -4
The answer is C. -4

2.  f(x) = (x − 4) + 5
f(1) = (1 - 4) + 5 
= (-3) + 5 = 2
The answer is B. 2

3. f(x) = 8 − 3(x + 2)
f(−6) = 8 - 3(-6 + 2)
= 8 - 3(-4)
= 8 + 12 = 20
The answer is A. 20

You have to find the angle i don’t know if i i try
