Verify whether the indicated numbers are zeros of the polynomials corresponding to them in the following cases:$ f(x)=5 x-\pi, x=\frac{4}{5} $

Given:

\( f(x)=5 x-\pi, x=\frac{4}{5} \)

To do: 

We have to find whether the indicated numbers are zeros of the polynomials corresponding to them.

Solution:

To find whether $x=\frac{4}{5}$ is a zero of $f(x)$ we have to check if $f(\frac{4}{5})=0$

Therefore,

$f(\frac{4}{5})=5 \times \frac{4}{5}-\pi$

$=4-\pi$

Therefore $x=\frac{4}{5}$ is not a zero of $f(x)$.
