Chapter 1: Q21. (page 67)

If $f (x) = 5 鈭� 2 x$ and $g (x) = x^{2} + 7 x$ , find each value.
$f (鈭� 6 y)$

Short Answer

Expert verified

The value of the $f (鈭� 6 y)$ is $5 + 12 y$ .

Step by step solution

Step 1. Given information.

We have a function $f (x) = 5 鈭� 2 x$

To find the value of $f (鈭� 6 y)$ .

Step 2. Apply the concept.

We substitute the value of the $x = 鈭� 6 y$ in the given function $f (x)$ and find the value of $f (鈭� 6 y)$ .

Step 3. Calculation.

Substitute $x = 鈭� 6 y$ in the function $f (x) = 5 鈭� 2 x$

localid="1641986722398" $f (鈭� 6 y) = 5 鈭� 2 脳 (鈭� 6 y)$

localid="1644933685684" $鈬� f (鈭� 6 y) = 5 + 12 y$

Hence, the value of the $f (鈭� 6 y)$ is $5 + 12 y$ .
