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
