Answer: f(-7)=41
Step-by-step explanation:
f(x) = x² + 2x + 6
f(-7)=(-7)² + 2(-7) + 6
f(-7)=49-14 + 6
f(-7)=35 + 6
f(-7)=41
Answer:
f(-7) = 41
Step-by-step explanation:
f(x) = x² + 2x + 6
In order to find f(-7) ,we just need to substitute x in the expression of the function f by -7.
Then
f(-7) = (-7)² + 2(-7) + 6
= 49 - 14 + 6
= 35 + 6
= 41
