Question

Find $p\left(4\right)\text{ and }p\left(-2\right)$ for the function $p\left(x\right)=2-x$.

Step-by-Step Solution

Answer

The value of $p\left(4\right)=-2\text{ and }p\left(-2\right)=4$.

Step 1. Write down the given information.

The given function is $p\left(x\right)=2-x$.

Step 2. Calculation.

Evaluating $p\left(4\right)\text{ and }p\left(-2\right)$ by plugging $x=4\text{ and }x=-2$ in given function $p\left(x\right)=2-x$.

$\begin{array}{c}p\left(x\right)=2-x \mathrm{....}\left(\text{Given}\right)\\ p\left(4\right)=2-\left(4\right)\\ =-2\\ \text{Now, }p\left(-2\right)=2-\left(-2\right)\\ =4\end{array}$

Step 3. Conclusion.

The value of $p\left(4\right)=-2\text{ and }p\left(-2\right)=4$.
