Does the graph represent a function? Choose the correct descriptor.

NO

Step-by-step explanation:

Thats an absolute value function, an absolute value function can not be negative

Not a function.

Step-by-step explanation:

Do the vertical line test. If a line can go from top to bottom and touch the line twice, then it is not a function. A line like this would touch twice on this graph, so it is not a function.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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.
