Chapter 1 - Speaking Mathematically - Exercise Set 1.3: 18

Answer

$h(-\frac{12}{5})=h(\frac{0}{1})=h(\frac{9}{17})=2$

Work Step by Step

The function is defined such that every real number is mapped onto the value 2 (i.e., $h(r)=2$). Recall that the variable $r$ is an arbitrary dummy variable. See page 20 for the description of this particular constant function.
