Question

find the equation of the inverse relation 2x^2+5y^2=4

Answer 1

if g(x) is the inverse of f(x), then
f(x) is the inverse of g(x)

since you were given the inverse already, to find the "function", just get her inverse :)

Answer 2

what?

Answer 3

do you know .... how to find an inverse?


you're asked for THE FUNCTION given her inverse function,

well, the inverse of an inverse function is THE FUNCTION

Answer 4

oops I had to modify the question

Answer 5

different wording, same meaning

Answer 6

so, you'd still get THE FUNCTION by getting the inverse of the given one

Answer 7

not sure how to acquire the right answer

Answer 8

to get the inverse of a function, all you do is a quick swap of the letters

\(\bf 2x^2+5y^2=4\qquad inverse \implies 2y^2+5x^2=4\)

then solve for "y"

Answer 9

well... I guess you can solve for "y" if you want... though as it's, it should be the inverse

but I gather what's being asked is the solution for "y"

Answer 10

nope all it asks for is to "Find the equation of the inverse relation" I didnt gather that it would be as simple as swapping letters.

Answer 11

an equation of an inverse relation is just a longer wording of saying "the inverse function", so the wording is just a bit convoluted, is all

Answer 12

Thanks for ALL your help and guidance!!!
