The function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3
<h3>How to determine the function that could be represented by Rebecca’s graph? </h3>
The properties are given as:
- The function is decreasing.
- The left end is approaching a constant.
For an exponential function to keep decreasing, one or more the following must be true:
- The rate is less than 1
- The leading factor is negative and the rate is greater than 1
For the left end of an exponential function to approach a constant, the following must be true:
- The leading factor is negative and the rate is greater than 1
The equation that has the above properties is f(x) =-2(5/4)^x+3
Hence, the function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3
