Question

Find the inverse of the function: f(x)=1/3x+4

Answer 1

the function can be written as y=(1/3)x+4. switch x and y, then solve for y (get it by itself)

Answer 2

how do you solve for y. i keep messing up somewhere

Answer 3

x=(1/3)y+4
subtract 4 from both sides
then multiply both sides by 3
what do you get?

Answer 4

where would you multiply 3

Answer 5

to get rid of 1/3 with the y, you multiply everything on both sides by 3.

Answer 6

oh that's right so the answer would be y=3x-12

Answer 7

yup
