Using the graph provided, find f(−2)

f(-2) = 1

Step-by-step explanation:

f(-2) means find the y value when x = -2

Going to x=-2 and going up until we hit the blue line

f(-2) = 1

Step-by-step explanation:

For f(-2), the input of the function f(x) is -2.

The input is the x value.

The output is the value of y.

When x = -2 on the graph, y = 1.

step-by-step explanation:

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.
