The graph of f(x) = 8(x8)25 is a parabola that opens --Select-- with its vertex at (x, y) = and f(8) = is the ---Select--- value of f. ' + x (a) Find the coordinates of the vertex and the x- and y-intercepts. vertex (x, y) = x-intercepts (x, y) = (x, y) = y-intercept (x, y) = (smaller x-value) (larger x-value) (b) Find the maximum or minimum value of f. The ---Select---▼value of f is f(x): = (c) Find the domain and range of f. (Enter your answers using interval notation.) domain range
