Question

If G(x) = 3x + 1, then G -1(1) is

4
1/3
0

Answer 1

i think it's 1/3

Answer 2

first find the inverse of G(x)

Answer 3

wrong

Answer 4

x-1/3

Answer 5

y = 3x + 1
3x = y - 1
x = (y- 1) / 3

g-1(x) = (x - 1) / 3

now plug in x =1 into the above and evaluate

Answer 6

you can also write g-1(x) as (1/3)x - 1/3

Answer 7

so 0

Answer 8

so g-1(1) = (1/3)*1 - 1/3

Answer 9

Yes 0 is correct

Answer 10

To find an inverse find x in terms of th function (y)

the replace the y by x in the final step

Answer 11

* then

Answer 12

OK?

Answer 13

ok thanks!
