Question

I require assistance on a troubling problem

Answer 1

Given data:

The given table.

The standard expression for the exponential function is,

`y=a(b)^x`

Substitute o for x and 5 for y in the above expression.

`\begin{gathered} 5=a(b)^0 \\ 5=a \end{gathered}`

Substitute 1 for x, 15 for y, and 5 for a in the standard exponential expression.

`\begin{gathered} 15=5(b)^1 \\ b=3 \end{gathered}`

The exponential expression can be written as,

`y=5(3)^x`

Thus, the expression for the exponential function is y=5(3)^x.
