Question

Find the inverse of the function.

f(x) = 7x + 2

Answer 1

just solve for x

Answer 2

=7x+2?

Answer 3

well if you are asked to change a function into inverse. Just replace the x with y or viceversa.

then, solve for the y.

y = 7x + 2

x = 7y + 2

x-2 = 7y

y = (x-2 )/ 7 <-- answer

Answer 4

f(x)=y=7x+2
1 x = (1/7)*y-2/7 sfx
2 y = (1/7)*x-2/7 swap x for y

Answer 5

noo i want the inverse of the function

Answer 6

so x+2/7

Answer 7

y = (1/7)*x-2/7 is inverse

Answer 8

^that is basically,

y = (x-2)/7

Answer 9

ok thank you i have a few more if u guys don't mind helping :/ &&& thank you

Answer 10

What is the aversion to leaving the inverse as a function of y? It is the same thing and is easier to differentiate.
