Prove that if n is an odd integer, then n^2 + 1 is an even integer.

n=3

9+1=10

n=1

1+1=2

n=5

25+1=26

a odd interger squared is a odd interger so if you add one its even

Hope This Helps!!!

idk

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
