The function g is defined piecewise on the set of real numbers. This means that the rule for g depends on the value of x. 9(x) = - 1 x+8 if x < 5 2 X-5 if x 5 For x in the subdomain (-, 5), the rule for g is given by g(x) = - 1 -x+8. For x in the subdomain ,), the rule for g is given by g(x) = x - 5.
