Joshua invests $500 at the interest rate shown. Felix invests $1,000 in an account with the same compounding but at 6% interest rate. Model each investment with an exponential growth function. Whose money will double first? Explain. INVESTMENT SPECIAL
Annual Interest Rate- 7.8%
Interest Period - 2 years

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

i can't solve unless i know what the line is

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.

the answer is c.
