SOLVED:(a) graph each quadratic function by determining whether its graph opens up or down and by finding its vertex, axis of symmetry; y -intercept, and x -intercepts, if any. (b) Determine the domain and the range of the function. (c) Determine where the function is increasing and where it is decreasing. f(x)=x^2 2 x

SOLVED:Find the two x-intercepts of the function f and show that f^'(x)=0 at some point between the two x-intercepts. f(x)=x^2+6 x
