f(x) = 2x^2 => f(x) = 2x^2 original function f(x) = x^2 Describe the graph and function behavior after the x is added. Explain in terms of function, inputs, outputs, and the graph. Solution Every value of y doubles. The graph looks like cup which gets narrower at the top. The original graph is the first graph The second graph is obtained by multplying 2.
