Which are characteristics of the graph of the function f(x) = (x + 1)2 + 2? Check all that apply. A) The domain is all real numbers.
B) The range is all real numbers greater than or equal to 1.
C) The y-intercept is 3.
D) The graph of the function is 1 unit up and 2 units to the left from the graph of y = x2.
E) The graph has two x-intercepts.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
