y = (4x+9)/(2x+3)
2xy+3y = 4x+9
3y-9 = 4x-2xy
3y-9 = x(2-2y)
x = (3y-9)/(2-2y)
So, inverse function is 3x minus 9 divided by 2 minus 27.
It is difficult to be certain. Limitations of the browser used by Answers.com means that we cannot see most symbols. Please resubmit your question spelling out the symbols as "plus", "minus", "equals". If the question is about xy = 7, then it is an equation of an inverse relationship. This is NOT the same as an inverse equation.
square root of x/pi
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.

fx=5x1 / 9
No. If you invert that function, it will produce an equation that gives you two return values for one input value. This does not meet the definition of a function.
To find the inverse, replace y with x, and x with y. So, the inverse of the equation is: x = 4yWhich is equal to:y = x/4
Assuming that b > 0, it is an inverse power function or an inverse exponential function.
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.
The inverse is not a function because it fails the vertical line test.
log5x
No, this is an inverse variation.
The inverse of an equation is rewriting it as a function of the other variable. Simply solve the equation for x instead of y. y=9x can be written as x= (1/9)y --> fy=y/9◄ y=4x+6 (or 4x+6=y) -> 4x=y-6 -> x=(y-6)/4 --> gy=(y-6)/4■
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
