We have the following functions:


\begin{gathered} f(x)=1-x^2, \\ g(x)=\sqrt[]{11-4x}\text{.} \end{gathered}

1) We evaluate (g · f)(2):


(g\cdot f)(2)=g(2)\cdot f(2)=\sqrt[]{11-4\cdot2})\cdot(1-2^2)=-3\cdot\sqrt[]{3}\text{.}

2) We evaluate (g + f)(2):


(g+f)(2)=g(2)+f(2)=(\sqrt[]{11-4\cdot2})+(1-2^2)=\sqrt[]{3}-3.

3) We evaluate (g - f)(-1):


(g-f)(-1)=g(-1)-f(-1)=\sqrt[]{11-4\cdot(-1)}-(1-(-1)^2)=\sqrt[]{15}\text{.}

4) We evaluate (f / g)(-1):


((f)/(g))(-1)=(f(-1))/(g(-1))=\frac{(1-(-1)^2)}{\sqrt[]{11-4\cdot(-1)}}=(0)/(4)=0.
