Help! How to solve it?

Question

 f(x)=x^2+1,  g(x)=x–4

 the value must be equal to (f*g)(10)

Answer 1

I think this way is correct:

f(x) = x² + 1

g(x) = x - 4

(f o g)(x) = (x - 4)² + 1

(f o g)(x) = x² - 8x + 16 + 1

(f o g)(x) = x² - 8x + 17

(f o g)(10) = 10² - 8(10) + 17

(f o g)(10 = 100 - 80 + 17

(f o g)(10)= 37
