(Hint: f – g)
Evaluate using f(x) = 4x - 9
21. f(-5)
22. g(-3)
g(x) = -4x2 h(x) = 5x . Show work.
23. f(2) - g(2)
24. h(a - 3)
25. Find the range of the function g(x) = x2 + 3 when the domain is {−5, 7}. Show work.
26. Find the domain of the function g(x) = x2 + 3 when the range is {19, 12}. Show work.
