Given f(x) = x2 + 5 and g(x) = 5x 2, solve the following functions:
15. f(6)
16. g(-2)
Indicate verbally what happens to the parabola f(x) = x2 in the following instance
17. - f(x 5)
MyPhoneCo, Inc. uses the following price schedule: x < 200 minutes, $.25 per minute; between 201 and 500 minutes, $.15 per minute; Over 501 minutes, $.10 per minute.

19. m = 5 and point (3, -10)
20. The line runs through (2, 3) and (-3, 7)
Given f(x) = x2 8x - 20 equation (parabola), find the following:
21. The vertex
22. The y-intercept(s)
Find the x-intercept(s) of the following equations
23. f(x) = 5x 13

If you invest $5,000 paying 9%, to the nearest penny how much will you have in 25 years if it is compounded:
25. semi-annually
26. continuously
Solve for x
27. log x = (2/3) log 8 (2 log 5 + log 2)
28. log (x 1) + log (x 1) = log 3
