Question

g (x) = -3x^4 + 6x^2 – xHow do I find the inverse function

Answer 1

$g(x)=-3x^4+6x^2-x$

We find the inverse function as follows, solving for y (Assuming g(x) as y):

The function is incredbly complex given the x^4, the x^2 and the x since there is not an easy way to factor it.

Explaining:

When you have a function:

$f(x)=6x-8$

(Here f(x)=y) You will determine the inverse function by solving for x:

$y=6x-8\Rightarrow y+8=6x\Rightarrow\frac{y+8}{6}=x\Rightarrow g(y)=\frac{y+8}{6}$

Here g(y) is going to represent the inverse function of f(x)
