Question

martin earns $23.89 per hour proofreading ads at a local newspaper.His weekly wage w can be describe by the equation w= 23.89h, where h is the number of hours worked (a). write the equation in function notation (b). find f(23) f(35) and f(41)

Answer 1

(a) The equation in function notation is

`\begin{gathered} w=23.89h=f(h) \\ w=f(h)=23.89h \end{gathered}`

Hence the answer is

`w=f(h)=23.89h`

(b). f(23) becomes

`\begin{gathered} f(h)=23.89h \\ f(23)=23.89*23 \\ f(23)=549.47 \end{gathered}`

f(35) becomes

`\begin{gathered} f(h)=23.89h \\ f(35)=23.89*35 \\ f(35)=836.15 \end{gathered}`

f(41) becomes

`\begin{gathered} f(h)=23.89h \\ f(41)=23.89*41 \\ f(h)=979.49 \end{gathered}`
