Question

If $f\left(x\right)=x^2-4$, find$f(-2).$

Short answer

So,$f(-2)=0.$

Step-by-step solution

Given Information

Given that$f\left(x\right)=x^2-4.$

Solution

Here, $f\left(x\right)=x^2-4$

localid="1645800513470" $$\begin{gathered} f(-2)={(-2)}^2=4 \\ f(-2)=4-4 \\ f(-2)=0. \end{gathered}$$

Final Answer

Hence,$f(-2)=0.$
