Answer: The exponential function would be
Step-by-step explanation:
Since we have given that
We have points (0,15) and (2,24)
First we take when x= 0, y = 15.
So, our equation becomes,
and we take when x = 2 and y = 240
So, the exponential function would be
The x intercepts are -2 and 5. First, you factor the equation and get (2x+4)(2x-10), then solve for the x's. If you have more problems like this, there's a great online calculator that can help with graphing. www.symbolab.com. It tells you the intercepts if you plug in the equations. Hope this helps!
