Largest Possible Value of y
If y = -x^2 + 3, what is the largest possible value of y?

I assume that it would be y=3 that you get when you put x=0. For the other values of x because it's negative you will start getting negative y, therefore i believe y=3 is the biggest value.

The function $y = -x^2 + 3$ is simply $y = x^2$ tipped upside down then moved up 3 places.
