Question

Consider the function f(x)=−23x+2f(x)=−23x+2 . What is f(12)f(12) ? Enter your answer, as a simplified fraction, in the box

Answer 1

F(12)= 278
f(12)= -274

Answer 2

Answer:

If the function is $f(x)=-23x+2$, then the value of f(12) is -274.

Note: If the function is $f(x)=-\frac{2}{3}x+2$, then the value of $f(\frac{1}{2})$ is $\frac{5}{3}$.

Step-by-step explanation:

The given function is

$f(x)=-23x+2$

Put x=12,

$f(x)=-23(12)+2=-274$

It is not a fraction value.

Note: If the given function is

$f(x)=-\frac{2}{3}x+2$

We have to find the value of $f(\frac{1}{2})$.

Put $x=\frac{1}{2}$ in the given function.

$f(\frac{1}{2})=-\frac{2}{3}(\frac{1}{2})+2$

$f(\frac{1}{2})=-\frac{1}{3}+2$

$f(\frac{1}{2})=\frac{-1+6}{3}$

$f(\frac{1}{2})=\frac{5}{3}$

Therefore the value of $f(\frac{1}{2})$ is $\frac{5}{3}$.
