Write an equation for the lowest-degree polynomial function with the graph and intercepts shown in the figure. For this exercise, make the leading coefficient be 1 or - 1. What is an equation for the polynomial function? f(x) f(x)

Graph the quadratic function f(x)=2x24x3 first using the properties as we did in the last section and then graph it using transformations. Which method do you prefer? Why

In the following functions, find (a) the equation of the axis of symmetry and (b) the vertex of its graph. 239. f(x)=x2+2x+5

An outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.

Explain why a polynomial function of odd degree must have at least one zero.
