ANSWER:
Given following piecewise functions (Defined on more than one intervals).
[tex]h(x)\text{ =}\begin{cases}x^2-1\text{ , x }\leq-1\text{ } \\ 4,\text{ -1 }We will evaluate these functions in order as f(x) , g(x) and finally h(x).Next these functions will be evaluated.
[tex]\begin{gathered} f(-\frac{7}{2})=-5 \\ g(4)=-3 \\ h(-\frac{1}{2})=-\frac{1}{2} \end{gathered}[/tex]NOTE! To evaluate h(x) at given x, we were required to evaluate g(x) at the same x value.
This is the result of evaluating three piecewise functions at specified x values, as it was asked in the question.!
