The function $f$ is decreasing in the interval $\underline{\left( 0,2 \right)}$
We know that if the values of y decrease when values of x increase then the function is said to be decreasing. In mathematical terms, the function is decreasing if $f\left( {{x}_{2}} \right){{x}_{1}}$ And the function is said to be decreasing in a particular interval, when the graph is going down in that interval. In the provided graph, it is decreasing during the interval $\left( 0,2 \right)$. Thus, the function $f$ is decreasing on the interval $\underline{\left( 0,2 \right)}$.
