In a exponential function:
![y=a\cdot b^x](https://img.qammunity.org/2023/formulas/mathematics/high-school/6has3k4sb3pm3ew4419r8bw5p19fprxq7e.png)
As any number powered to o is equal to 1:

The y-intercept in exponential functions is a coordinates (0,a).
b represents the exponential growth or decay :
If 0
If b> 1 the function represnet a exponential growth
Exponential part (x in this case) represents how fast the function increase or decrease
For the given graphs:y intercpets: A (0,4) and B (0,6) Y intercept of graph B is greather than y intercept in graph AAs both functions have the same exponential part (x). Both graphs rise at the same rate
