Accepted Solution

A:

Answer:(1) [tex]f(x)=3x+4[/tex]Ad g(x) represent f(x) after horizontal translation 2 units to the left.[tex]g(x)=3(x+2)+4[/tex][tex]g(x)=3x+6+4[/tex][tex]g(x)=3x+10[/tex] is the required translation.(2) [tex]f(x)=\frac{-2x}{3}+2[/tex][tex]f(\frac{1}{2})=\frac{-2}{3}\cdot(\frac{1}{2})+2[/tex][tex]f(\frac{1}{2})=\frac{5}{3}[/tex](3) We have been given a point (1,-9); slope 2We will use the equation:[tex]y-y_1=m(x-x_1)[/tex]m is the give slope.[tex]y-(-9)=2(x-1)[/tex][tex]y+9=2(x-1)[/tex]Therefore, Option (a) is correct.
