Question

Let f(x)= 3x - 1 and g(x)=x^2 + 1

Find (f o g) 7).
Then (fog)(7) = 1. (Simplify your answer.)

Answer 1

Explanation:

I do not fully understand your question yet

assuming this is what you asked

f(x) = 3x-1 and g(x) = x² +1

f o g(7) = f( g(7)) = f( 7² +1) = f( 50) = 3*50 -1 = 149

(f o g) (7) = f(g(x))(7) = f( x²+1)(7) = ( 3x²+3-1) (7) = (3x²+2)(7) ...
