Answer 4

you are given 3 points, see which option they fit

Answer 5

we can narrow the options if we know how the graph behaves. graphs decrease for values between 0 and 1 as the 'rate'.

Answer 6

is it D?

Answer 7

if you mean the last one, the points dont fit for that:

3(1/2)^(2-1) is not 9

Answer 8

27(1/3)^(2-1) does = 9, and the other points fit it as well.

Answer 9

But do you plug in the points given?

Answer 10

you can, thats a good way to check it out

Answer 11

i notice that the options are all exponent functions

the graph gets smaller as x gets bigger, so the value being exponeted has to be between 0 and 1 .. only 2 options work

testing the point 2,9: 3/2 = 9 is false, so 27/3 = 9 has to be the one we want

Answer 12

ohhhhhhhh ok now i get lol thank you for your help! :)
