Question

How do you write an exponential function whose graph passes through (0,3) and (1,15)?

Answer 1

I got `y=3e^(xln(5))`

Explanation:

I would try to use the coordinates of your points:

Our function maight be:
`y=3e^(xln(5))`
Or using `ln(5)=1.61`
`y=3e^(1.61x)`

Graphically:
graph{3e^(1.61x) [-9.84, 10.16, -9.32, 0.68]}
