What is the range of f?
0 -15 O y> 15
Oy> 35
O all real numbers

The range of a function y = f(x) is the set of values y takes for all values of x within the domain of f. The graph of any quadratic function, of the form f(x) = a x 2 + b x + c, which can be written in vertex form as follows f(x) = a(x - h) 2 + k , where h = - b / 2a and k = f(h)
