Question

If f(x) = x2 + 1 and g(x) = x – 4, which value is equivalent to mc024-1.jpg

Answer 1

x²-2

Explanation:

on edg

Answer 2

Given that f(x)=x^2-1 and g(x)=x-4, the value of (f*g)(10) will be:
f*g=(x^2-1)(x-4)
=x^2(x-1)-1(x-4)
=x^3-x^2-x+4
=x^3-x^2-x+4

next we find (f*g)(10), we substitute the value of x in our expression.
(f*g)(10)=10^3-10^2-10+4
=894
