Prove that n2 + I ≥ 2n when n is a positive integer with 1 ≤ n ≤ 4.

C

(0,−3)

E

(5,−2)

Step-by-step explanation:

We need to find a point in the shaded region

A

(−4,1)

x = -4 is not in the shaded region

B

(−3,−4)

x = -3 is not in the shaded region

C

(0,−3)

Since the bottom line is solid, this is in the shaded region

D

(0,1)

Since the line is dotted, this is not in the shaded region

E

(5,−2)

This point is in the shaded region
