Question

MEDAL!

Which of the following values are in the range of the function graphed below? Check all that apply.

(Picture below.)

Answer 1

Would it be -1, 0, and 1?

Answer 2

@marcoduuuh do you what the 'range' of a function is? Any idea at all?

Answer 3

Where the line passes by?

Answer 4

Nope. 'Range', as the word suggests, is a list of all values this function (or its graph) can take. That is all values of 'y'. Now, which of -1,0 or 1 are present in the graph of the function?

Answer 5

0 and 1?

Answer 6

I can see that red curve passing through y='1', and I can't see it anywhere near y=0. So, what do you think?

Answer 7

OOPS SORRY! Yeah, only 1.

Answer 8

The answer was 0 and 1. /:

Answer 9

Haha! What? I tricked you c'mon - the curve touches y=0 at TWO points --> x=1 and x=-1 BOTH. You should have noticed this maaaan!
(sorry for the tricky thing, I wanted you to understand this thing)

Answer 10

Ughhhh i need to pay attention next time! Thanks for the help!
