Simple silly math question......?

Question

what is the inverse of the equation

y= - 4x -36

Answer 1

y+36 = -4x <-- Solve for x

x = -(36+y)/4

y = -(36+x)/4 <-- Interchange x and y to get inverse

Answer 2

4x=-y-36

x= (y-36)/4

or

f' ^-1   (x)= (x-36)/4

hint: find x

Answer 3

hi angel, here...

to find the inverse of a function, you need to be able to modify the equation so the X will become the subject(a variable being left alone on one side).

in your question the Y is the subject, got it?

then ...

y = -4x - 36

y + 4x = -36

4x = -y - 36

x = -y/4  - 9

then the inverse is ( just replace the y with x )

y = -x/4 - 9.

done...

see ya

Answer 4

Solve for x

y + 36 = -4x

(y + 36)/-4 = x

x = -y/4 - 9
