Answer 1

Talk me through it and why, please :)!

Answer 2

How about I tell you a very short and easy method??

Answer 3

Ok. @FaiqRaees :D

Answer 4

Take any value of x (that lies in the domain) and put in the function and note the value of y. Do it with 2,3 more values of x and note down the values for y. Then compare all the graphs and check which one satisfies all the values.

Answer 5

In this question, you can narrow down the answer just by using x = 6 and x =3

Answer 6

Still don't get it ;-:

Answer 7

y =1/3|x|-2 y =1/3|x|-2
y = 1/3x|6|-2 y = 1/3 x|3|-2
y = 2-2 y = 1 -2
y = 0 when x =6 y = -1 when x =3
So the correct graph should contain the points (6,0) and (3,-1)

Answer 8

D

Answer 9

Perfect so now you get it?

Answer 10

Looking at the points 6,0 and 3, -1. How did you figure that stuff out?

Answer 11

Figure which stuff out?

Answer 12

y =1/3|x|-2 y =1/3|x|-2 y = 1/3x|6|-2 y = 1/3 x|3|-2 y = 2-2 y = 1 -2 y = 0 when x =6 y = -1 when x =3
