Question

Write an exponential equation for the graph.

Answer 1

Explanation:

Exponential equations can be written as

`y = ab^x\\`

in this case,

a = 5000 (the starting amount)

we just have to find b

`10000 = 5000b^4\\20000 = 5000b^8\\\\b^4 = 2\\b^8 = 4\\\\\\b = \sqrt[4]{2}`

`y = 5000(\sqrt[4]{2})^x`
