Respuesta :

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
