How to find the zeros of a function on a graph After plotting the cubic function on the graph we can see that the function h(x) = x^{3} - 2x^{2} - x + 2 cut the x-axis at 3 points and

Find the zeros of the quadratic function f is given by f(x) = -2 x 2 - 5 x + 7. Solution to Example 2 Solve f(x) = 0 f(x) = -2 x 2 - 5 x + 7 = 0 Factor the expression -2 x 2 - 6 x + 8 (-2x - 7)(x - 1) = 0 and solve for x x = -7 / 2 and x = 1 The graph of
