22. f(x) = 3x - 2x + 1

a. f(0) b. f(1)
c.f(-1) d. f(10)
e.f(-3) f. f(2a)

24. g(t) = |t - 1|

a) g(4) b) g(-2)
c) g(-1) d) g(100)
e g(5a) f) g(a + 1)

JUST READ THIS PROBLEM BUT DON'T ANSWER BUT USE IT FOR 28.
27. The function H described by H (x) = 2.75x + 71.48 can be used to determine the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long. If a humerus is known to be from a female, how tall was she if the bone is (a) 32cm long? (b) 35 cm long?

28. Refer to Exercise 27. When a humerus is from a male, the function

M9x) = 2.89x + 70.64 can be used to find the male's height, in centimeters. If a humerus is known to be from a male, how tall was the male if the bone is (A) 30 cm long? (B) 35 cm long?
