The graphics below represents a function
what is the value of (4)

C) 0

This is the x intercept because y = 0 here. The full location is (x,y) = (4,0)

Effectively, you draw a vertical line through x = 4 to see where it crosses the function curve. Call this point P. Then from point P, you draw a horizontal line to the y axis to see what the y coordinate of that point is. In this case, P = (4,0).

found it xd it ok yt

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
