Option A:

Solution:

A composite function is created when one function is substituted into another function.

Given and

To find which expression represents .

Substitute f(x) into the function g(x).

Here in place of x. So expand it using .

Option B is the correct answer.

Hence .

true

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
