For each function, make a table using x-values – 3, 0, and 5. Graph the function.
a. f(x) = -2x – 6 b. g(x) = 2(1.5)x + 4
Factor the expressions:
a. 256x2 – 96x b. 10x2 + 19x - 15

3. Warm Up 2/28/17 3. Use the quadratic formula to solve:
2y2 + 2y - 11 = 0
Find the inverse of f(x) = x – 5 4
(Hint: Switch the x and y and solve for y.)

9. Jane bought a car that cost $24,520. Her vehicle depreciates at a rate of 9% each year. How many years will it take for Jane to have a car that is worth less than $5,000? How much is her car worth after 10 years?
Find the rate of change over the interval
[-2, 5] for the function: f(x) = 40(.5)x
