for f(x)=-|x+2|, find f(-8)

Question

find the function value

Answer 1

To find the value of f(-8), just replace the x in the function with -8

f(-8) = -l-8 + 2l

f(-8) = -l-6l

f(-8) = -6

 

Answer 2

f(x) = - |x+2|, substitute x = -8 to get
f(-8) = - |-8 +2|
f(-8) = - |-6|, absolute value of a negative number is a positive number
f(-8) = -6
