(a) $f(x)=\frac{3}{4}(x-4)$ (b) $\begin{array}{ccc} \\x &f(x) \\-4 &-6 \\0 &-3 \\4 &0 \\8 &3 \end{array}$ (c) Refer to the attached image below for the graph.
(a) Algebraic Representation Subtract 4 from the input, where the input is $x$, means $x-4$. Thus, the algebraic representation of the function is: $f(x)=\frac{3}{4}(x-4)$ (b) Numerical Representation Create a table of values to have: $\begin{array}{ccc} \\-4 &-6 \\0 &-3 \\4 &0 \\8 &3 \end{array}$ (c) Graphical Representation Plot each ordered pair in the table of part (b), then connect the points using a line. (Refer to the attached image below for the graph.)
