Question

Jeff believes that the following expression will always yield a value that is greater than 2.

2x + 1
Is Jeff correct? Explain why or why not and provide three examples that prove whether or not Jeff's statement is correct

Answer 1

Jeff is Incorrect

Explanation:

If x ≤ 1/2, the value will either be 2 or less than 2.

x = 1/2 => 2(1/2)+1 = 2

x = 0 => 2(0)+1 = 1

x = -1 => 2(-1)+1 = 0
