Unformatted text preview: element in a set B. Let f be the function defined by: f(x) = -2x 2 + 2x. Then • f(0) = • f(1) = • a + f(a) = • f(a + h) = If a graph can be intersected in more than one point by a vertical line, then the graph is NOT the graph of a function. • • Evaluate h(2) where h = g f and f(x)= x 2 +x +1; g(x) = x 2 • h(2) = _________ The Difference Quotient...
