Question

Find the range of the given function y = 5x - 4, where x > 6.

Answer 1

Given:

The function is:

$y=5x-4$

where $x>6$.

To find:

The range of the given function.

Solution:

Range is the set of output values.

We have, $x>6$. It means the value of x is greater than 6 but not equal to 6.

The function is

$y=5x-4$

Putting x=7, we get

$y=5(7)-4$

$y=35-4$

$y=31$

Putting x=8, we get

$y=5(8)-4$

$y=40-4$

$y=36$

Putting x=9, we get

$y=5(9)-4$

$y=45-4$

$y=41$

So, the range of the given function is {31, 36, 41...}.

Therefore, the correct option is B.
