Assuming it's a linear equation, y= -1/2x
So first, you subtract 9 and 4, which gives you 5. Then, you add that to 5. That gives you 10.

Y=x. I hope that this helped! Good luck! :)
First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.
