Question

Let f (t) be the population of rabbits on Christy's property t years after she received 12 of them as a gift.
t f(t)
0 12
1 22
2 50
3 64
4 71
5 72
Compute the following. (If there is not enough information to tell, enter NONE.) f -1 denotes the inverse function of f.
(a) f(2)


(b) f -1(50)


(c) f -1(72)


(d) 5 · f -1(71)


(e) f -1(3 · 50)


(f) f(71)


(g) f -1(8)

Answer 1

which part(s) do you not understand here?

Answer 2

what am i supposed to do

Answer 3

just started doing this so im not too keen on this yet

Answer 4

they have given you a table of values for "t" and "f(t)"
so for (a) they are asking what is the value of "f(2)". this means t=2. so look in the table for t=2 and read off the value for f(t) along that row.

Answer 5

o thats all? thats pretty straight forward

Answer 6

yes - and f-1(x) just means the exact opposite. i.e. find x under the f(t) column and read off the value of "t" on the same row.

Answer 7

what about the ones that are not on the chart?

Answer 8

like (d) through (g)

Answer 9

(d) is there

Answer 10

(d) states 5.f-1(71) which translates to "5 times the value of t for the row that contains 71 for f(t)"

Answer 11

o it is

Answer 12

5 * 4 = 20

Answer 13

yeah got ya

Answer 14

good

Answer 15

what about the others

Answer 16

Answer 17
