If


\begin{gathered} f(x)\text{ =2x-1} \\ \text{and} \\ g(x)=2-x^2 \\ \end{gathered}

Then,


\begin{gathered} 1.\text{ f(0)=2(0)-1 = -1} \\ 2.\text{ f(12) = 2(12)-1 = 23} \\ 3.\text{ f(-2) = 2(-2)-1= -5} \\ 4.g(-1)=2-(-1)^2=1 \\ 5.g(4)=2-(4)^2=-14 \\ 6.\text{ f(d) = 2(d) - 1 = 2d - 1} \end{gathered}
