The graph of a quadratic function fis given. F(x)=x-2x + 6 vertex A 10 domain 5 (a) Find the coordinates of the vertex and the x and y-intercepts. (x, y) = x-intercepts (x, y) = (x, y) = y-intercept (x, y) = (b) Find the maximum or minimum value of f. The-Select-value of F is f(x) = range 1 x (smaller x-value) ) (larger x-value) (c) Find the domain and range of f. (Enter your answers using interval notation.)
