Question
![**Problem: Finding an Exponential Function**
Objective: Determine the formula for an exponential function that passes through given points.
Points provided:
- Point 1: \((-2, \frac{4}{25})\)
- Point 2: \((1, 20)\)
**Task:**
Find and input the equation of the exponential function \(y = ab^x\) that includes these points.
1. **Substitute each point into the exponential function formula to create a system of equations.**
For \((-2, \frac{4}{25})\):
\[
\frac{4}{25} = ab^{-2}
\]
For \((1, 20)\):
\[
20 = ab^1
\]
2. **Solve the system of equations for \(a\) and \(b\).**
Use these equations to determine the constants. This will result in the exponential function describing the given points.
Please fill in the solution in the provided field labeled \(y =\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F370ea171-8bb9-4b07-85c5-04ae9f865ef9%2Fd9d01201-b5ec-4c9f-a85c-516d09091903%2F9jzdylr_processed.jpeg&w=3840&q=75)
