Question

given h(x)=-x+5, solve for x when h(x)=3

Answer 1

Answer:

x is 2

Step-by-step explanation:

• When h(x) is 3, the whole functional equation is equated to 3

${ \rm{ {}^{ - }x + 5 = 3 }} \\ \\ { \rm{ {}^{ - }x = 3 - 5 }} \\ \\ { \rm{ {}^{ - }x = {}^{ - } 2}} \\ \\ { \boxed{ \rm{ \: x = 2}}}$
