it's not right

what would happen if you plugged in x=1 ? you get\[x^2\ge1\implies x\ge1\]\[1^2\ge1\implies1\ge1\]where is the falsehood here?

I agree with @TuringTest 1 does equal 1.

ohh yeah.. it wouldnt b false.
anonymous

but its saying OR equal to
TuringTest
  • TuringTest
and it is equal, so it's true

@Emah yeahh thats true.. i dont see another answer that works

try each one individually

oh oops i sdidnt see the part that said couterexample:( sorry

ohh its okk

what do you get when you plug in x=2\[x^2\ge1\]\[x\ge1\]are both still true?
anonymous
  • anonymous
i get that its false
TuringTest
  • TuringTest
which part is false?
anonymous
  • anonymous
first part
TuringTest
  • TuringTest
\[2^2\ge1\]is not true you say?
anonymous
  • anonymous
Im confused
TuringTest
  • TuringTest
we need to find an example where the first part is true, and the second part is false to disprove the statement
TuringTest
  • TuringTest
\[2^2=4\]and four is greater than one, so \[x^2\ge1\]is true for x=2
TuringTest
  • TuringTest
what about the other part, is\[2\ge1\]?
anonymous
  • anonymous
its true because 2 is greater tha 1
TuringTest
  • TuringTest
right, so both statements are true for x=2, so this is not a counterexample
TuringTest
  • TuringTest
what about for x=-3 is\[x^2\ge1\]and is\[x\ge1\]?
anonymous
  • anonymous
first one is 9 > 1 (true) second one is 3 > 1 (true too)
anonymous
  • anonymous
so than its 1/4 (:
