If x > 0, find the range of number x-3, 3x+2,x-1, 4x, 2x-1, x-2, 2x-2, 3x and 3x+1
- A.
3x+3 - B.
3x+1 - C.
2x+5 - D.
2x+1
Correct Answer: Option C
Explanation
x-3, 3x+2,x-1, 4x, 2x-1, x-2, 2x-2, 3x, 3x+1
Range = 3x+2 – (x-3)
= 3x+2 – x – 3
= 2x + 5
x-3, 3x+2,x-1, 4x, 2x-1, x-2, 2x-2, 3x, 3x+1
Range = 3x+2 – (x-3)
= 3x+2 – x – 3
= 2x + 5
