Answer:

Consider the function : [tex]f(x) = -\frac{2}{3}x +5[/tex]                 ......[1]

To find the value of [tex]f(\frac{1}{2})[/tex].

We put [tex]x = \frac{1}{2}[/tex] in equation [1] to solve for [tex]f(\frac{1}{2})[/tex].

then;

[tex]f(\frac{1}{2}) = -\frac{2}{3}(\frac{1}{2})+5 = -\frac{1}{3} + 5 = \frac{-1+15}{3} =\frac{14}{3} =4\frac{2}{3}[/tex]

The function [tex]f(\frac{1}{2})[/tex] is the simplified form is,  [tex]4\frac{2}{3}[/tex]

If [tex]f(x)=\frac{-2}{3}x+5[/tex], then [tex]f(\frac{1}{2})=4\frac{2}{3}[/tex]

The given function is:

[tex]f(x)=\frac{-2}{3}x+5[/tex]

To find the value of [tex]f(\frac{1}{2} )[/tex], substitute x = 1/2 into [tex]f(x)=\frac{-2}{3}x+5[/tex]

[tex]f(\frac{1}{2})=\frac{-2}{3}(\frac{1}{2})+5[/tex]

By simplifying the expression above we have:

[tex]f(\frac{1}{2})=\frac{-1}{3}+5[/tex]

This will result to:

[tex]f(\frac{1}{2})=\frac{14}{3}[/tex]

In mixed number form:

[tex]f(\frac{1}{2})=4\frac{2}{3}[/tex]

Therefore, if [tex]f(x)=\frac{-2}{3}x+5[/tex], then [tex]f(\frac{1}{2})=4\frac{2}{3}[/tex]
