Answer 1

Answer:

d. $4x^2-7$

Step-by-step explanation:

The given functions are

$f(x)=4x+1$ and $g(x)=x^2-2$

We want to find the composition of the f and g.

$f(g(x))=f(x^2-2)$

We substitute $x^2-2$ into $f(x)=4x+1$ to obtain;

$f(g(x))=4(x^2-2)+1$

This simplifies to;

$f(g(x))=4x^2-8+1$

$f(g(x))=4x^2-7$

Hence the correct choice is d.
