can be the form of the exponential function.
Two points are (-2,25) and (1, 8/5).

Take logarithms of both sides, base of your choice, and you will have a linear equation. You would need to make an adjustment to the vertical axis component of your given points.

You'll need to change the data points to (-2, ) and (1, ), for whatever base you choose.
If chosen to take logs base 10, then you will have your LINEARIZED points as (-2, 1.39794) and (1, 0.20412).

The rest of the solution process relies on both linear equation skills and logarithm, exponential expression skills and concepts.

You should find or if desired, .
