33. A function is defined by g(a)= -2a + 7, and its domain is the set of integers from 1 through 30, inclusive. For how many values of a is g(a) negative?

Answer and Explanation

Your Answer is

Correct Answer is B

Explanation

Because the original function is monotonically decreasing in the domain of definition, and it is greater than 0 when a=3, and less than 0 when a=4, so only when a is an integer greater than or equal to 4 and less than or equal to 30, g(a) is less than 0. There are 27 in total.
