Answer 1

Answer: c) 5

Explanation:

just took the test goodluck <3

Answer 2

f(-2) = 5

Explanation:

we are given with a function f(x) = - 4x – 3

we are asked to determine

f(-2)

in order to find f(-2) we will substitute x = -2 in our function f(x)

f(x)=-4x-3

f(-2) = -4(-2)-3

=8-3

=5

Hence f(-2) = 5
