The number of feet that a car travels before stopping depends on the driver's reaction time and the braking distance, as shown below. For one driver, the stopping distance is given by the polynomial function f(v) = 0.03v² + 0.4V where v is the velocity of the car. Find the stopping distance when the driver is traveling at 30 mph. | ft Stopping distance d Reaction time Braking distance Decision to stop © Robert E. Daemmrich/Getty Images

Given the function 2x^4 − x^3 − 45x^2 − 27x + 135, factor and graph the equation. Make sure tostate the degree, leading coefficient, end behaviour, domain, and range. Graph using theturning points, which you must solve for. Graph paper on the next page.
