Chapter 1: Q38. (page 50)

Examples 4 and 5 If $f (x) = - 2 x - 3$ and $g (x) = x^{2} + 5 x,$ find each value. (P. 50)
$f (0) - 7$

Short Answer

Expert verified

The value of the function $f (0) - 7$ is $- 10$ .

Step by step solution

Step 1. Interpreting of function.

$f (0)$ Indicates the value of function $f (x)$ at $x = 0$

Step 2. Apply substitution method.

Substitute $x = 0$ into the function $f (x)$

$\begin{array}{l} f (0) = - 2 (0) - 3 \\ f (0) = - 3 \end{array}$

Step 3. Further calculation.

$\begin{array}{l} f (0) - 7 = - 3 - 7 \\ f (0) - 7 = - 10 \end{array}$

Therefore, the value of the function $f (0) - 7$ is $- 10$ .
