Answer 3

Check the graph:- What is the value of y when the line approaches x = 1

Answer 4

- approaching from the negative values

Answer 5

the vale of y would be 1, correct?

Answer 6

No - its below the x axis

Answer 7

oh, -1, sorry

Answer 8

thats correct y or f(x) = -1 up to and including x = 1 ( the filled circle means x = 1 is incleded)

Answer 9

Now check the right side of y axis - what is the value of y from x = 2 on?

Answer 10

I am confused on what you mean by x= 2 and on...

Answer 11

I know the coordinate of the x would be (3, 2)

Answer 12

the line starting from x = 2 and continuing to the right

Answer 13

yes that means y = 3 when x = or > 2

Answer 14

So now you can see which is correct option

Answer 15

so y would continue to be -1?

Answer 16

No its above the x axis :- y = 3

Answer 17

oh wait, would the answer be B

Answer 18

No
the value of f(x) changes according to value of x NOT y

Answer 19

f(x) ( or y) = -1 when x <= 1
and
f(x) = 3 when x >= 2

Answer 20

oh, so it would be A then, if its based on the value of x?

Answer 21

B sya 'when y'

Answer 22

YES A is correct

Answer 23

is it clear now?

Answer 24

yes it is, thank you so much!
