Question

For f(x)=2x+1 and g(x2-7 find f/g (x)

Answer 1

Option c.

Explanation:

We are given these following functions:

`f(x) = 2x + 1`

`g(x) = x^2 - 7`

Division:

The division of those functions is:

`(f)/(g)(x) = (2x + 1)/(x^2-7)`

Domain:

We have a fraction, so we have to take the domain of the function in consideration. The denominator cannot be 0, thus:

`x^2 - 7 \\eq 0`

`x^2 \\eq 7`

`x \\eq \pm √(7)`

Thus, the correct answer is given by option C.
