The graph of a quadratic function f is given. f(x) = 2x² + 4x - 3 (a) Find the coordinates of the vertex and the x- and y-intercepts. (Round your answers to one decimal place.) (x,y)=(-1,-5 x) vertex x-intercepts (x, y) = (0.581, 0 (x, y) = ( y-intercept (x, y) = (b) Find the maximum or minimum value of f. The minimum ✔✔ value of f is f(x) = X domain range (smaller x-value) (larger x-value) (c) Find the domain and range of f. (Enter your answers using interval notation.)
