Answer:
the answer is 3
Step-by-step explanation:
function notation is the way a function is written.
Using an exponential function, it is found that f(5.5) = 19.8.
<h3>What is an exponential function?</h3>
An exponential function is a function in which the growth rate is a percentage, modeled by:

In which:
f(3.5) = 25 means that:


f(8.5) = 14 means that:

Hence:


![b = \sqrt[5]{\frac{14}{25}}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7B14%7D%7B25%7D%7D)


Hence, the function is given by:

Then, when x = 5.5:

She worked 7.5 hours a day on average. You can get this by dividing the 37.5 by 5.
And the average she made was 118.13 when rounded. You can get this by multiplying the 7.5 by the rate
Both graphs x =4 and y =4 will be perpendicular to each other.
- The graph of x = 4 is a vertical line down the Graph scope
- The graph of y =4 is a horizontal line side the Graph scope.
Both the Lines will meet exactly at ( 4, 4 ) perpendicularly at each other both of them intersecting at 90 degrees.
Vertical and Horizontal lines are perpendicular to each other (90 Degrees).
