If x is a positive number and y = x^2, then which of the following is true?
a) y is always more then x
b) x is always more then y
c) x is always equal to y
d) none if these

• when x=1 and y=1 then option d is correct.

• d) none of these
  as :
  y is always more than x becomes false in case of x=1 (y=1^1=1) (x becomes equal to y)
  x is always more than y and x is always equal to y becomes false in case of x=2 (y=2^2=4)(y becomes greater than x)

• d. as (0.2)^2=0.04

• none of these is ALLWAYS true
• 9 years agoHelpfull: Yes(4) No(0)
• if we take fraction value of x say 0.5 the answer is y=0.25 so first option is neglected
  since by the first assumption x(square)is always less so option d is correct

• option a because the square of any number will be greater than the number itself.

• square of x can be greater or to y as x is positive no. so it can be 1 also.

• a) y is always more than x.
  if u double the number it will be always greater

• option d) if x=1 ,then y=1^2=1(y is equal to x)
  if x=2,then y=2^2=4(y is greater than x)
• 9 years agoHelpfull: Yes(0) No(0)
• it means y=square of x so ,option a is correct
• 8 years agoHelpfull: Yes(0) No(1)
• x is positive number so square of positive is always greter than that number
• 8 years agoHelpfull: Yes(0) No(0)
• y is always more then x
• 8 years agoHelpfull: Yes(0) No(1)
• d) NOT because when x=0.1 y is 0.01 and when x=1 y is also 1 also when x=2 y is 4
  so no option matches
• 8 years agoHelpfull: Yes(0) No(1)
• y is always morethan x since it is square of x.
