Given:
Function is:
![2x-5\ge3](https://img.qammunity.org/2023/formulas/mathematics/college/jjb0u5y969q4lk8z6at0n2tmvgp1422c4o.png)
Find-:
Check the value of "x" for the function is valid.
Explanation-:
The function is:
![2x-5\ge3](https://img.qammunity.org/2023/formulas/mathematics/college/jjb0u5y969q4lk8z6at0n2tmvgp1422c4o.png)
Solve the function for "x."
![\begin{gathered} 2x-5\ge3 \\ \\ 2x\ge3+5 \\ \\ 2x\ge8 \\ \\ x\ge(8)/(2) \\ \\ x\ge4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/qyfk0ynf9i0bb7tml2578uejc61ww1qwnx.png)
When the value of "x" is greater and equal to 4, the function is True.
Check for given "x" is:
![\begin{gathered} x=-2\rightarrow\text{ False} \\ \\ x=0\rightarrow\text{ False} \\ \\ x=2\rightarrow\text{ False} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/fq2syibfaukd03issauqzls8l3hh3x6xrn.png)
The above value of "x" is less than four; the function is False.
The value of "x" at -2, 0 and 2 are function is False.
![\begin{gathered} x=4\rightarrow\text{ True} \\ \\ x=6\rightarrow\text{ True} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/j9ch1n3niuzjg614ko4qcfdjob3tmu933i.png)
The value of "x" at 4 and 6 are function is True.
