Given the function:
[tex]g(x)=3-x^2,\text{ }x\in\Re[/tex]You have to evaluate g(2), this means that you have to replace the equation of the function with x=2 and solve:
- First, replace x=2 into the equation
[tex]\begin{gathered} g(x)=3-x^2 \\ g(2)=3-2^2 \end{gathered}[/tex]- Next, solve the exponent and then the difference to find the value of g(2)
[tex]\begin{gathered} g(2)=3-2^2 \\ g(2)=3-4 \\ g(2)=-1 \end{gathered}[/tex]The value of g(x) when x=2 is -1.
