Chapter 7: Q26. (page 350)

Find $p (4) and p (- 2)$ for the function $p (x) = x^{4} - 7 x^{3} + 8 x - 6$ .

Short Answer

Expert verified

The value of $p (4) = - 166 and p (- 2) = 50$ .

Step by step solution

Step 1. Write down the given information.

The given function is $p (x) = x^{4} - 7 x^{3} + 8 x - 6$ .

Step 2. Calculation.

Evaluating $p (4) and p (- 2)$ by plugging $x = 4 and x = - 2$ in given function $p (x) = x^{4} - 7 x^{3} + 8 x - 6$ .

$\begin{matrix} p (x) = x^{4} - 7 x^{3} + 8 x - 6 .... (Given) \\ p (4) = {(4)}^{4} - 7 {(4)}^{3} + 8 (4) - 6 \\ = - 166 \\ Now, p (- 2) = {(- 2)}^{4} - 7 {(- 2)}^{3} + 8 (- 2) - 6 \\ = 50 \end{matrix}$

Step 3. Conclusion.

The value of $p (4) = - 166 and p (- 2) = 50$ .
