8: SBAC EXERCISES

PART A.

Given the function g(x) = x 2 -6x -16,
which statement is true?
A: The zeros are -8 and 2,
because the factors are (x+8) and (x-2).
B: The zeros are -8 and -2,
because the factors are (x+8) and (x+2).
C: The zeros are -2 and 8,
because the factors are (x+2) and (x-8).
D: The zeros are 2 and 8,
because the factors are (x-2) and (x+8).

Part B.

The graph models the linear relationship between the number
of monthlypayments made on a loan and the remaining and the
remaining balamnce in dollars left to pay on the loan.


Based on the graph, select the correct answer.

A: The x intercept is 60, which represents
the initial balance in dollars of the loan.
B: The x intercept is 27,000, which represents
the initial balance in dollars of the loan.
C: The x intercept is 60, which represents the
number of monthly payments needed to repay the loan.
D: The x intercept is 27,000, which represents the
number of monthly payments needed to repay the loan.
