Question

y=log1/3 (x−1)−2
I have to find the domain and range for this and match it to the right graph

Answer 1

lets look at differently

Answer 2

what does -2 do to your graph? does it move it right 2, left 2, up 2 or down 2?

Answer 3

left 2 i think

Answer 4

when the number is outside of the function it moves it up or down

Answer 5

-2 is down 2
whereas
+2 would have been up 2

Answer 6

so down 2 is the correct response

Answer 7

Oh ok

Answer 8

x-1 now x is a liar or I have been told
this one is moved left or right 1 unit be careful x is a liar it goes in the opposite direction you would think it does

Answer 9

so it moves right 1

Answer 10

yes right one and down 2

Answer 11

your reference point is (1,0) from your parent function

Answer 12

your parent function is log 1/3(x)

Answer 13

take (1,0) and move it right one unit and down 2 units where does it end up

Answer 14

2,-2

Answer 15

ok go look for that one point on your choices, which one is it?

Answer 16

C

Answer 17

yes it is. Learn your transformations and then you can apply it to any function. Most reference points are (0,0) but I had to use my graphing calculator to figure this function's reference point.

Answer 18

Thank you so much
