Given f x please help me set them up and stuff

Answer:
See Explanation
Step-by-step explanation:
[tex]f(x)=\sqrt{-4x+4}[/tex]
put each value from the chart into the equation and solve
[tex]f(-2)=\sqrt{-4(-2)+4}\\f(-2)=\sqrt{8+4}\\f(-2)=\sqrt{12} \\f(-2)= 3.46[/tex]
[tex]f(-1)=\sqrt{-4(-1)+4}\\f(-1)= \sqrt{4+4} \\f(-1)=\sqrt{8} \\f(-1)= 2.83[/tex]
[tex]f(0)=\sqrt{-4(0)+4}\\f(0)= \sqrt{0+4} \\f(0)=\sqrt{4} \\f(0)= 2[/tex]
[tex]f(1)=\sqrt{-4(1)+4}\\f(1)= \sqrt{-4+4} \\f(1)=\sqrt{0} \\f(1)= 0[/tex]
[tex]f(2)=\sqrt{-4(2)+4}\\f(2)= \sqrt{-8+4} \\f(2)=\sqrt{-4} \\f(2)= DNE[/tex]
