Answer:
An increase of 43.3% per year
Step-by-step explanation:
using the equation, plug in the respective variables. 650 =500R3, 3 times 500 is 1500. 650=1,500R. divide both sides by 1500 to get .4333, 3 repeating. .433 in percent form is 43.3%. (I just use 650 out of 500 or 650/500 which is 1.3 divided by 3 because 3 years to get the same amount)

![\boxed {\boxed {\sf C. \ (0,2)}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20C.%20%5C%20%280%2C2%29%7D%7D)
Step-by-step explanation:
The y-intercept of a graph occurs when the function cross the y or vertical axis. This is also where x is equal to 0.
Therefore, we can substitute 0 in for x and solve for y.
![y= 2(4^x)](https://tex.z-dn.net/?f=y%3D%202%284%5Ex%29)
![y= 2(4^0)](https://tex.z-dn.net/?f=y%3D%202%284%5E0%29)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve the exponent. Any number raised to the power of 0 is equal to 1.
![y= 2(1)](https://tex.z-dn.net/?f=y%3D%202%281%29)
Multiply.
![y=2](https://tex.z-dn.net/?f=y%3D2)
The y-intercept is 2. So, when x=0, y=2.
Coordinate points are written as (x, y). The y-intercept is <u>(0,2).</u>
