The answer is 11.5 (please mark me as brainliest if true)
Answer:
4x - 16
Step-by-step explanation:
X can be any value (I made it 20)
5.5(2)+ 1 - (1.5(2) +17)
11 + 1 - 20
12 -20
-8
4(2) - 16
8 - 16
-8

B is your answer to the question
First of all, you figure out that -4 < 3, so you use the first function definition. Then you put -4 wherever you see x.
.. f(-4) = (-4)^2 -5
.. = 16 -5
.. f(-4) = 11
