Question

Given f (x)=9.2x +11, what is f (12)? If it does not exist, enter DNE

Answer 1

Given:-

`f(x)=9.2(x)+11`

To find:-

`f(12)`

So to find the required value. we substitute 12 for x. so we get,

`\begin{gathered} f(x)=9.2(x)+11 \\ f(12)=9.2(12)+11 \\ f(12)=110.4+11 \\ f(12)=121.4 \end{gathered}`

So the required solution is 121.4
