![60. CCSS CRITIQUE Chris and Tobias are finding (fog)(x), where f(x) = x² + 2x-8
and g(x) = x² + 8. Is either of them correct? Explain your reasoning.
Chris
Tobias
(fog)(x) = f(g(x)]
= (x²+8)² + 2x-8
= x² + 16x² +64 + 2x - 8
= x² + 16x² + 2x + 58
(fog)(x) = f(g(x)]
= (x² + 8)² + 2(x² + 8) -8
= x² + 16x² +64 + 2x² + 16-8
= x + 18x² + 72](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd9449f52-23ff-4dfa-b62d-d5f2140918c3%2F8e306f0b-39ae-441d-9fd3-8b0e48b1dc9c%2Fmjn9v7_processed.jpeg&w=3840&q=75)
