Question

please help I'm having trouble figuring out finding the inverse of a function on this problemf(x)=5x+3over 4

Answer 1

f(x) is y so put the equation equal to y then make x the subject
when you do interchange x and y and that should be the inverse

Answer 2

let me know what you got

Answer 3

so x= 5y+3over 4

Answer 4

no

Answer 5

jus to be sure the original equation is f(x) = 5x + 3/4 right?

Answer 6

yes

Answer 7

right so replace f(x) with y so the equation will be y= 5x +3/4

Answer 8

y - 3/4 = 5x

Answer 9

(y - 3/4) all over 5 = x
x is now the subject . now where you see x you put y and where you see y you put x
so the inverse of f(x) = x- 3/4 all over 5

Answer 10

ok i understand now thank you
