Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x − 2)? (4 points) The graph of y = f(x) will shift left 2 units.

The graph of y = f(x) will shift right 2 units.

The graph of y = f(x) will shift up 2 units.

The graph of y = f(x) will shift down 2 units.

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
