Question

Function g defined by g(x)=3-x^2 , x ER evaluate:g(2)

Answer 1

Given the function:

$g(x)=3-x^2,\text{ }x\in\Re$

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

$\begin{gathered} g(x)=3-x^2 \\ g(2)=3-2^2 \end{gathered}$

- Next, solve the exponent and then the difference to find the value of g(2)

$\begin{gathered} g(2)=3-2^2 \\ g(2)=3-4 \\ g(2)=-1 \end{gathered}$

The value of g(x) when x=2 is -1.
