Question

Help a brother out :')​

Answer 1

Steps to solve:

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

~Solve the exponent and multiply

f(-3) = 9 - 12

~Subtract

f(-3) = -3

~Find the absolute value

|f(-3)| = |-3|

~Simplify

|f(-3)| = 3 (Third Option)

Best of Luck!

Answer 2

3

Explanation:

f(x) = x^2 +4x

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

=9-12

=-3

|f(-3) | = |-3|

The absolute value is the positive value

|f(-3) | = 3
