For f (x) = 3x +1 and g(x) = x^2-6, find (g/f)(x)
sp2606 [1]

Answer:

(g/f) (x) =\frac{x^2-6}{3x+1}

Step-by-step explanation:

We have the following functions

f (x) = 3x+1

g (x) = x^2-6

To find (g/f)(x) we must divide the function g(x) with the function f(x)

Then we perform the following operation

(g/f) (x) =\frac{x^2-6}{3x+1}

Finally we have that:

(g/f) (x) =\frac{x^2-6}{3x+1}

For x \neq -\frac{1}{3}
