Question

2. Rainey graphed a function with exponential growth and an initial value of 15. Which of the following could represent the equation Rainey graphed?

Answer 1

Exponential equation are functions defined by $y =ab^x$

The equation that could represent Rainey graph must take the form $y =15b^x$

How to determine the equation

An exponential equation is represented as:

$y =ab^x$

Where:

• a represents the initial value
• b represents the rate

The initial value (a) is 15.

So, the equation becomes

$y =15b^x$

The graph is not given;

So, the equation cannot be determined.

Assume that the rate is 2.

Then the function would be: $y =15(2)^x$
