28. A reflection over the x-axis maps AABC to AA'B'C'. Do the preimage and image have the same size and shape?
Explain.
Choose the correct answer below.
A. No. A reflection preserves only lengths of sides.
B. Yes. A reflection preserves both angle measures and
lengths of sides.
C. No. A reflection preserves neither angle measures nor
lengths of sides.
D. No. A reflection preserves only angle measures.

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.
