Well, looking at the expression, it has a -5 on the leading term, that means is not just a quadratic, but is a parabolic graph and because the coefficient of the leading term is negative, is upside-down, or opening downwards.
because it opens downwards, it looks like an arc, comes from the bottom up up up gets to a "maximum" or U-turn (vertex), then goes back down down down. So, where's the vertex anyway?

so, that's where the vertex is, and the maximum value for f(x), is the y-coordinate of course, or 9.
The answer is c because I took a great guess im putting the answer because I know no-one else would put the answer for this person when they need the answer but I need the answer so I took a great guess
