Chapter 4: Q48. (page 158)

Find each value if $f (x) = x^{2} - 3 x + 2$ .
48. $f (2)$

Short Answer

Expert verified

The value of $f (2)$ is 0.

Step by step solution

01

– Description of step.

Compare $f (2)$ to $f (x)$ .

By comparing $f (2)$ to $f (x)$ , it can be concluded that the value of $x$ is 2.

02

– Description of step.

Substitute 2 for x into $f (x) = x^{2} - 3 x + 2$ .

$f (2) = {(2)}^{2} - 3 (2) + 2$

03

– Description of step.

Simplify the equation obtained in step 2 to find the value of $f (2)$ .

\begin{matrix} f (2) = 4 鈭� 6 + 2 \\ = 鈭� 2 + 2 \\ = 0 \end{matrix}

Therefore, the value of $f (2)$ is 0.
