Chapter 2: Q2. (page 74)

2. Find the value of $f (15)$ if $f (x) = 100 x - 5 x^{2}$ . (Lesson 2-1)

Short Answer

Expert verified

The value of $f (15)$ is 375.

Step by step solution

– State the concept

The value of $f (a)$ can be obtained by substituting a for each $x$ in the expression for $f (x)$ .

– List the given data

The function $f (x) = 100 x - 5 x^{2}$ . The objective is to find $f (15)$ .

– Evaluate the required value

Put $x = 15$ in $f (x) = 100 x - 5 x^{2}$ to get,

$\begin{matrix} f (15) = 100 (15) 鈭� 5 {(15)}^{2} \\ = 1500 鈭� 5 (225) \\ = 1500 鈭� 1125 \\ = 375 \end{matrix}$

So, $f (15) = 375$ .

Thus, the value of $f (15)$ is 375.
