A social networking site has an estimate 5000 members.This number is expected to increase 80% each month. Which function and graph model the number of members in thousands over time in months?

Answer:
y = 5(1.8)^x
Step-by-step explanation:
the formula for an exponential equation is y = a(b)^x
the a in this case is the starting number which is 5000
y = 5000(b)^x
the b is the percentage in decimal form
0.8 BUT it is an increase so we add 1
1.8
y = 5000(1.8)^x
because the graph is in thousands we can make 5000 into 5
