Question

if f(x)= -4x+1, find f(-5)

Answer 1

subs -5 for x in f(x)

Answer 2

finding f(-5) means put x=-5 in f(x)

Answer 3

the |a| means absolute value.
Ex. of Absolute value
1. |-x| = x
2.|+x| = x
3. |-35| = 35

then f(x) = |x+1| substitute -5 to x
we get
f(-5) = |-5+1|
f(-5) = |-4|
Then
f(-5) = 4 <<< Final Answer
