The graph of f(x) = 4(x - 5)^2 - 7 is a parabola that opens ---Select--- , with its vertex at (x, y) = ( ), and f(5) = is the ---Select--- value of f.
Adi S.
Find the vertex of each parabola. For each equation, decide whether the graph opens up, down, to the left, or to the right, and whether it is wider, narrower, or the same shape as the graph of $y=x^{2}$. If it is a parabola with a vertical axis of symmetry, find the discriminant and use it to determine the number of $x$ -intercepts. $$ f(x)=-x^{2}+7 x+2 $$
