GRE - Quantitative Reasoning - Relations and Functions

Quantity A: x2 + 2x + 1 (more)

Quantity A: x2 2x 1
 
Quantity B: x2
 
• Quantity A is greater.
• Quantity B is greater.
• Both Quantities are Equal
• Cannot be determined

Quantity A - Quantity B = 2x + 1

2x + 1 > 0 for x > -1/2

2x + 1 = 0 for x = -1/2

2x + 1 <0 for x < -1/2

So it cannot be determined with the given information. More information is needed to find a complete solution.

Option D

If |t+3| > 5, which of the following could be the value of t ? (more)

If |t 3| > 5, which of the following could be the value of t ? 

Indicate all such values.

A. −9

B. −6 

C. −2

D. 0

E. 2

F. 3

|t + 3| > 5

Case 1 Case 2

t + 3 > 5

t > 8

-(t + 3) > 5

t + 3 < - 5

t < - 2

 

Possible solutions are options A and B
