A linear function y = f(x) has an x-intercept of -9 and a y-intercept of 2. The function undergoes the transformation y = f(x+h), h +0. Compared to the function y = f (x), the transformation of y = f (x +h) will have _ i to the x-intercept and ii _to the y-intercept. 9. The statement above is best completed by the answers in row: Row i ii a change a change no change no change no change a change a change no change

2. The height, h, in feet, of an object thrown upward from a height of 144 feet is a function of time, t, in seconds. The height can be determined by the function h(t) = -16t^2 + 128t + 144. What is the height of the object at 3 seconds? * (25 Points) %3D h(t) = -161 + 1281 + 144 Enter your math answer

A study by the National Highway Traffic Safety Administration found that driver fatality rates were highest for the youngest and oldest drivers. The rates per 1000 licensed drivers for every 100 million miles may be approximated by the function ƒ(x) = k(x - 49)6 + 0.8, where x is the driver’s age in years and k is the constant 3.8 * 10-9. Find and interpret the rate of change of the fatality rate when the driver is a. 20 years old; b. 60 years old
