Answer:
3
Step-by-step 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
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!
