Given that x is a nonnegative number, a student conjectured that x + 3 < x2. Which value of x is a counterexample to the student's conjecture?
A: x= -1/3
B: x= -3
C: x= 2
D: 3

C (x = 2)

Step-by-step explanation:

Since x is a non-negative number, A and B are eliminated.

This leaves C and D.

C: x = 2,

2 + 3 < 2^2

5 < 4 is false.

So C would be a counterexample.

Hope this helps!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
