f(-3)=-7

1) To evaluate a function is to plug one value for x, and find the corresponding f(x) value.

2) Since f(x)= 2x-1 we can evaluate f(-3) this way:

[tex]\begin{gathered} f\mleft(-3\mright)=2\mleft(-3\mright)-1 \\ f(-3)=-6-1 \\ f(-3)=-7 \end{gathered}[/tex]

3) So as we can see when we plug x=-3 we have -7 as the corresponding value.

And that is the answer
