The graph of a quadratic function fis given. f(x) = 2x2 -4x - 4 y 5 1 X Un (a) Find the coordinates of the vertex and the x- and y-intercepts. (Round your a vertex ( x, y ) = 1, - 6 x-intercepts ( x, V ) = (smaller x-value) X ( x, y ) = (larger x-value) X y-intercept (x, y ) = (b) Find the maximum or minimum value of f. The minimum v value of fis f(x) = -6 (c) Find the domain and range of f. (Enter your answers using interval notation.) domain (-00,00) range (-00, ]
