Answer 2

Pretty sure this one is either a or b

Answer 3

Why do you think it's A or B?

Answer 4

I used desmos to graph the functions, and A and B looked closest. I jus can't tell which one.

Answer 5

OK. But we have to actually work things out and not go by the looks of a desmos graph. (the choice of scale can distort things)

Answer 6

Ok

Answer 7

For example, one of the points on the given graph is (-2, 1). See it?

Answer 8

Yes

Answer 9

OK. Try substituting x=-2 into the given functions and see which ones return 1 for f(x).

Answer 10

C does right?

Answer 11

Not quite\[f(x) = |-2-2| = |-4| = 4\]

Answer 12

Oh wait D does right?

Answer 13

no

Answer 14

oH WAIT I THINK IT IS

Answer 15

That's right. Well done. Desmos can be a help, but you mustn't rely on it entirely.

Answer 16

So the answer is D?

Answer 17

Correct.

Answer 18

Yes because the 1/2 does the recipical, so x2 and multiplies the value of x by 2
