Answer
The values of x when the value of the function is 1 are:
$f\left( x \right)=1$, $x=\frac{1}{2}$ and$\frac{3}{2}$.
Work Step by Step
Observe the graph of the function, $y=f\left( x \right)$
To find the values of x such that $f\left( x \right)=1$, observe the y-axis and see where the point 1 is marked.
Now, move to the x-axis to find the corresponding x-coordinate.
Observe that at $x=\frac{1}{2}$, the y-coordinate is 1; also at $x=\frac{3}{2}$, the y-coordinate is 1.
Therefore, for the two values of x, the y-coordinate is 1.
Thus, the values of x when the value of the function is 1 are:
$f\left( x \right)=1$, $x=\frac{1}{2}$ and$\frac{3}{2}$.
