Unformatted text preview: to find the y intercept, let x = 0. i.e. f(0) is the yintercept. 5. Find a plot more points if necessary to see the shape of the graph. 6. Check that there are the correct number of zeros and turning points and that the graph crosses and touches the xaxis where it should. Graph. h(x) = x 3x Graph g(x) = x 3 + 2x 2 + 4x 8 The Intermediate Value For any polynomial function P(x) with real coefficients, if a b and P(a) and P(b) are of opposite signs, then the function has a real zero between a and b. This means that the graph of the function either crosses or touches the xaxis between a and b. Use the intermediate value theorem to determine. if possible, whether the function f has a real zero between a and b. f(x) = 2x 57x + 1; a = 1, b = 2...
