Question

Evaluate the following function for f(12).f(x)=-3/4x-7

Answer 1

Given the function :

`f\mleft(x\mright)=-(3)/(4)x-7`

To find the value of f(12), substitute with x = 12 at the given function

`\begin{gathered} f(12)=-(3)/(4)\cdot12-7 \\ f(12)=-3\cdot3-7 \\ f(12)=-9-7 \\ \\ f(12)=-16 \end{gathered}`
