Question

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

A: {-30, -35, -40...}
B: {31, 36, 41...}
C: {-31, -36, -41...}
D: {30, 35, 40...}

Explain how you got this step by step. a lot of you like to give false answers just for points but I really need help understanding this. Please don't answer if you arent sure Any attempt is appreciated.

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.
