Hope this helps ;) I had the test too and it was right
Answer:c
Step-by-step explanation:
Answer:
f(-3) = 16
Given:
f(x) = 2x² + x + 1
Required:
f(-3)
Solution:
Substitute x = -3 into f(x) = 2x² + x + 1
f(-3) = 2(-3)² + (-3) + 1
f(-3) = 2*9 - 3 + 1
f(-3) = 18 - 3 + 1
Steps to solve:
x - 12 = 40
~Ad 12 to both sides
x = 52
Best of Luck!
