Question

** What is the value of T 6) for the function Rx)=x-??

Answer 1

We have the function:

`f(x)=(1)/(2)x-7`

And want to now the value of f(-6), so we need to evaluate the function f(x) at x=-6, this means replace x by -6 in the expression of f(x), so:

`\begin{gathered} f(-6)=(1)/(2)\cdot(-6)-7 \\ f(-6)=-(6)/(2)-7 \\ f(-6)=-3-7=-10 \end{gathered}`

So f(-6) = -10
