Find the vertex of the parabola x = -2y^2 + 5y + 7. I'm confused, because x is a function of y.
This is a SIDEWAYS parabola.... you find the vertex the same way as before
the 'y' coordinate of the vertex is given by - b/2a where b = 5 and a = -2
use this value of 'y' in the equation to find the 'x' coordinate of the vertex......
