The piecewise function is formed by three lines and the following results are found:
- f (- 3.0001) = 3
- f (3.999) = 7
- f (4.0001) = - 3
- f (9) = Undefined
How to analyze piecewise functions
Piecewise functions consists in a conditional combination of functions, all related to given subintervals. It is to notice that black ends indicate that a given function contains an end, whereas white ends do not.
By direct observation we obtain a piecewise function formed by three horizontal linear functions:
f(x) = 3, - 9 ≤ x ≤ - 3
f(x) = 7, 3 < x ≤ 4
f(x) = - 3, 4 < x < 9
Now we proceed to evaluate the piecewise function:
f (- 3.0001) = 3
f (3.999) = 7
f (4.0001) = - 3
f (9) = Undefined
