If [tex]x = -3[/tex], which domain category does it fit into?
[tex]x \leq -1[/tex]
Find [tex]f(-3)[/tex]:
Since [tex]-3 \leq -1[/tex], the answer to [tex]f(-3)[/tex] will be -6, as this is the part of the function that matches with [tex]x \leq -1[/tex]. When you have just a constant for a part of a piecewise function, any input (x-value) that falls within that domain will always yield the constant value. Thus, [tex]f(-3) = -6[/tex] and similarly, [tex]f(-4) = -6[/tex].
If [tex]x = -1[/tex], which domain category does it fit into?
Find [tex]f(-1)[/tex]:
Notice that for [tex]x \leq -1[/tex], the value -1 is included. The other category, [tex]-1 \ \textless \ x \ \textless \ 3[/tex], does not include -1 or 3. Because of the inequality signs, [tex]f(-1) = -6[/tex] as well.
If [tex]x = 2[/tex]:
Which domain category does it fit into?
Find [tex]f(2)[/tex].
