MA240 College Algebra1. Determine whether the equation defines a function with independent variable x. If it does find the domain. If it does not find a value of x to which there corresponds more than one value of y.2. Use the graph of the function to estimate:a. f(2) b. f( 4) c. All x such that f(x) = 03. For the following graph:a. Find the domain of f. b. Find the range of f.c. Find the x-intercepts.d. Find the y-intercept.e. Find the intervals over which f is increasing.f. Find the intervals over which f is decreasing.g. Find the intervals over which f is constant.h. Find any points of discontinuity.4. Use the following to answer questions a-d:f(x) = x2 + x and g(x) = x 5a. Find h(x) = (f g)(x).b. State the domain of h(x) = (f g)(x).c. Find h(x) = (g f)(x).d. State the domain of h(x) = (g f)(x).
