I need help on this. please

Step-by-step explanation:

So we have:

And we want to find the quotient q(x). Thus:

Substitute:

Factor the numerator:

Substitute:

The (x+2)s cancel out. Therefore:

However, we must restrict x such that it cannot equal -2.

In the original equation, if it did, our answer would be undefined. Thus, our final answer is:

And we are done :)

Edit: Typo

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
