Answer:
Step-by-step explanation:
The exponential function is . is the initial value of the function, or the y-value when x=0. In this case, =5. If we enter that into the equation:
Then we can use another point to solve for .
Since anything raised to the power of 1 remains the same, we can continue to solve algebraically.
Now that we have both the and value, we can return to the exponential function and fill in the blanks.
I hope this helps!
