Answer:
y = 10 * 2^x
OR
y(5) = 10 * 2^5
Day 0 = 10 pennies: Point(0, 10)
Day 1 = 20 pennies: Point(1, 20)
Day 2 = 40 pennies: Point(2, 40)
Day 3 = 80 pennies: Point(3, 80)
Day 4 = 160 pennies: Point(4, 160)
Day 5 = 320 pennies: Point(5, 320)
Step-by-step explanation:
Heath has 10 pennies, so pennies = 10.
He doubles the number of pennies each day, so total pennies = 10 * 2 to the power of # of days.
Using the equation y = 10 * 2^x will give you the answer for any number of days. Since the problem asks for 5 days, you plug in 5 for x. On the graph, this would be a single point (5, 320).
So, plot the 6 points you have and connect a curved line through it. That should be your answer.
