Answer:
![f(x)=0.7(5)^x](https://tex.z-dn.net/?f=f%28x%29%3D0.7%285%29%5Ex)
Step-by-step explanation:
![\text{Exponential function: }y=a\cdot b^x](https://tex.z-dn.net/?f=%5Ctext%7BExponential%20function%3A%20%7Dy%3Da%5Ccdot%20b%5Ex)
It is two types of function.
- Exponential Growth: If function increase as value of x increase.
In this case, a>0 and b>1
- Exponential decay: If function decrease as value of x increase.
In this case, a>0 and 0<b<1
We need to choose exponential growth function.
![\text{Exponential Growth function: }f(x)=0.7(5)^x](https://tex.z-dn.net/?f=%5Ctext%7BExponential%20Growth%20function%3A%20%7Df%28x%29%3D0.7%285%29%5Ex)
Here a=0.75>0 and b=5>1
Therefore, This function is exponential growth.
Answer:
