Chapter 7: Q25. (page 350)

Find $p (4) and p (- 2)$ for the function $p (x) = x^{5} - x^{2}$ .

Short Answer

Expert verified

The value of $p (4) = 1008 and p (- 2) = - 36$ .

Step by step solution

Step 1. Write down the given information.

The given function is $p (x) = x^{5} - x^{2}$ .

Step 2. Calculation.

Evaluating $p (4) and p (- 2)$ by plugging $x = 4 and x = - 2$ in given function $p (x) = x^{5} - x^{2}$ .

$\begin{matrix} p (x) = x^{5} - x^{2} .... (Given) \\ p (4) = {(4)}^{5} - {(4)}^{2} \\ = 1008 \\ Now, p (- 2) = {(- 2)}^{5} - {(- 2)}^{2} \\ = - 36 \end{matrix}$

Step 3. Conclusion.

The value of $p (4) = 1008 and p (- 2) = - 36$ .
