The graph of a quadratic function f is given. f(x) = 4x- 8x-1 y 5 X 1 5 (a) Find the coordinates of the vertex and the x- and y-intercepts. (Round you vertex (x, y) = ( x-intercepts (x, y) = ( (smaller x-value) (x, y) = (larger x-value) y-intercept (x, y) = (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
