Question

Find f(-5) f(x) -4x + 3

Answer 1

if f(x)= -4x+3

f(-5)= 23

Explanation:

first you substitute x for -5

f(-5)= -4(-5)+3

then you multiply

-4(-5)

f(-5)=20+3

you get the positive 20 because negative times negative equals positive

then you just add the rest (20+3) which will give you your answer

f(-5)= 23
