I have 2 problems that i think are probably solved the same way...

Given that the point

is on a graph of the function

and that

is an odd function, find another point on the graph of

Given that the point

is on a point on the graph of the function

and

Now i know

(x)=

(x) means it's even and

(x)=-

(x) means it's odd.. but how do i come up with the function to input the (x,y) values?

(x)=x^3......

-8=-7^3......

then re-arrange and solve for .......?

Thanks
