Chapter 2: Q49. (page 61)

Find each value if $f (x) = 3 x - 5$ and $g (x) = x^{2} - x$ .
$f (\frac{2}{3})$

Short Answer

Expert verified

The value of $f (\frac{2}{3})$ is $- 3$ .

Step by step solution

– Select the correct function.

_{The given functions are:}

$\begin{array}{l} f (x) = 3 x 鈭� 5 \\ g (x) = x^{2} 鈭� x \end{array}$

_{The required function for the value $f (\frac{2}{3})$} is $f (x) = 3 x - 5$ .

– Substitute the value in the selected function.

Substitute $x = \frac{2}{3}$ in the function $f (x)$ .

$f (\frac{2}{3}) = 3 (\frac{2}{3}) - 5$

– Calculate the value by simplification.

$\begin{array}{l} f (\frac{2}{3}) = 3 (\frac{2}{3}) 鈭� 5 \\ f (\frac{2}{3}) = 2 鈭� 5 \\ f (\frac{2}{3}) = 鈭� 3 \end{array}$

Thus, the value of $f (\frac{2}{3})$ is $- 3$ .
