Height and Headcircumference: The headcircumference C of a child is related to the height H of the child(both in inches) through the function:
H(C) =2.15C-10.53
(a) Express the head circumference C as a function of heightH
(b)Verify that C=C(H) is the inverse of H=H(C) by showing thatH(C(H))=H and C(H(C))=C.
(c)Predict the head circumference of a child who is 26 inchestall.

Find the inverse of a piecewise function, namely:
$f (x) = {\begin{cases} x - 1, & 0 \leq x < 1 \\ 2 - x, & 1 < x \leq 2 \end{cases}$
For the first case
$f : y = x - 1$ when $0 \leq x < 1 \to f^{- 1} : x = y + 1$ when $- 1 \leq x < 0$
But I find this because I only have to subtract 1 from the endpoints of the inequality. I don't have a clear intuition how to do this with 2−x

Dealing with function Math questions is never easy as these can be implemented virtually anywhere where Algebra is used. It means that starting with at least one function Math example from what has been provided below will help you. Of course, certain function Math problems will require more analysis and verbal explanations, yet these are also encountered as you look through the questions. Learn about the use of equations first! The functions Math problems are always based on the analytical part because the function Math equation always has only one answer for every unknown variable.
