The piecewise-defined function with linear parts f(x)= |2x + 9|
f(x) = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
<h3>How to write piecewise functions?</h3>
To write this function as a piecewise function, you have to use the definition of absolute value.
The absolute value equation is; f(x)= |2x + 9|
The definition says that;
|x| = {x x ≥ 0)
{-x x < 0}
Applying this definition to the function you get:
|2x + 9| = {2x + 9 2x + 9 ≥ 0)
{-2x - 9 2x + 9 < 0}
After simplifying the inequalities you get:
|2x + 9| = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
So finally you can write the piecewise function as:
f(x) = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}

Answer:
The answer to your question is: $4.15
Step-by-step explanation:
To find the mean we just have to sum all the values and divide them by the number of data.
mean = (5.25 + 3.50 + 4.50 + 4.00 + 3.50) / 5
mean = 20.75/5
mean = $ 4.15
