Answer:
If the function is [tex]f(x)=-23x+2[/tex], then the value of f(12) is -274.
Note: If the function is [tex]f(x)=-\frac{2}{3}x+2[/tex], then the value of [tex]f(\frac{1}{2})[/tex] is [tex]\frac{5}{3}[/tex].
Step-by-step explanation:
The given function is
[tex]f(x)=-23x+2[/tex]
Put x=12,
[tex]f(x)=-23(12)+2=-274[/tex]
It is not a fraction value.
Note: If the given function is
[tex]f(x)=-\frac{2}{3}x+2[/tex]
We have to find the value of [tex]f(\frac{1}{2})[/tex].
Put [tex]x=\frac{1}{2}[/tex] in the given function.
[tex]f(\frac{1}{2})=-\frac{2}{3}(\frac{1}{2})+2[/tex]
[tex]f(\frac{1}{2})=-\frac{1}{3}+2[/tex]
[tex]f(\frac{1}{2})=\frac{-1+6}{3}[/tex]
[tex]f(\frac{1}{2})=\frac{5}{3}[/tex]
Therefore the value of [tex]f(\frac{1}{2})[/tex] is [tex]\frac{5}{3}[/tex].
