Question

What is the range of the function for the given domain?

y = 2x - 5
D: (-2,0, 2,4}
Select the correct answer.
OR: {-9, 0,-1,3}
OR: {9,-5, 9, 13}
OR: {-9, -5, -1,3}
OR: {-9, 0, 9, 13}

Answer 1

Explanation:

Answer 2

`\boxed{ \bold{ \huge{ \boxed{ \sf{ - 9 \: , \: - 5 \: , - 1 \: , \: 3 \: }}}}}`

Option C is the correct option.

Explanation:

Here, y = 2x - 5 and domain ( D ) = { -2 , 0 , 2 , 4 )

when, x = -2 , Range = 2 × (- 2)- 5 = - 4 - 5 = -9

when, x = 0 , range = 2 × 0 - 5 = 0 - 5 = -5

when x = 2 , range = 2 × 2 - 5 = 4 - 5 = -1

when, x = 4 , range = 2 × 4 - 5 = 8 - 5 = 3

Range = { -9 , -5 , -1 , 3 }

Hope I helped!
