Question

Find the inverse of the function. Enter NO INVERSE if no inverse exists.
f (x) = 8x2 + 9

Answer 1

x=8y^2+9
x-9=8y^2
(x-9)/8=y^2
square root ((x-9)/8)=y

Answer 2

the answer is NO INVERSE

Answer 3

Oh.. then I don't know sorry :(

Answer 4

Well you have to specify the domain!

Answer 5

Below is quotation from Purple Math site
http://www.purplemath.com/modules/invrsfcn2.htm:
"Since the original function had two points that shared the same Y-VALUE, then the inverse of the original function will not be a function. This means, for instance, that no parabola (quadratic function) will have an inverse that is also a function."
