Use the intermediate value theorem to show that the function has a zero between the two numbers given. Then, use your calculator to approximate the zero to the nearest hundredth. P(x) = 8x# - 12x- + 16x - 20; 1 and 1.5 Evaluate the function for the lower bound, 1. P(1) = (Type an integer or decimal rounded to the nearest hundredth as needed.)
