We will determine the value output of a function for an input value.
The given function is given as:
[tex]\begin{gathered} \textcolor{#FF7968}{V}\text{\textcolor{#FF7968}{ ( x ) = 12 - 2x - 5}} \\ \end{gathered}[/tex]The function is defined in terms of an input value ( x ). The function gives us an output for every defined set of values ( domain ).
We will evaluate the function given for a value of input:
[tex]\textcolor{#FF7968}{x}\text{\textcolor{#FF7968}{ = -2}}[/tex]To evalaute any function for any defined input value is substituting the respective value into input variable ( x ) in the function relationship as follows:
[tex]\begin{gathered} V\text{ ( - 2 ) = 12 - 2}\cdot\text{ ( -2 ) - 5} \\ V\text{ ( -2 ) = 12 + 4 - 5} \\ \textcolor{#FF7968}{V}\text{\textcolor{#FF7968}{ ( -2 ) = 11}} \end{gathered}[/tex]Hence, the evaluated output of the function at ( x = -2 ) is:
[tex]\textcolor{#FF7968}{11}[/tex]
