The graph shows the linear parent function . Which statement best describes the function? A. The function is negative when x<0 and also when x>0
B. the function is never negative
C. the function is negative when x>0
D. The function is negative when x<0

Using function concepts, it is found that the correct option is given by:

D. The function is negative when x<0

In this problem, the graph of the function is the red line, and:

Thus, option D is correct.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
