Determine if the point (−1,2) is on the graph of f(x)=4x2−x−3. Find the value of f(2) and the point on the graph. Find x when f(x)=−3 and the point(s) on the graph. Determine the domain of f(x), the x-intercept(s), and the y-intercept. Choose the correct answer for whether the point (−1,2) is on the graph.
