Given ƒ(x) = x - 1, complete parts a and b.
part a: using the table provided, create five points to demonstrate that for the function, ƒ(x) = x - 1, there is exactly one output value for each corresponding input value. in your final answer, include all calculations and the completed table.
x y
part b: on a separate sheet of paper, use the points created in part a to graph the function, ƒ(x) = x - 1. label the values on the x- and y-axes, and all points on the graph.

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.

where are the graphs?
