How do you determine an equation for the inverse of a function Example f of x equals 9x or g of x equals 4x plus 6?
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■

Find the inverse variation equation if x equals 5 when y equals 9?
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
Inverse function 2x plus 4?
y=2x+4 --> x=2y+4 ==> y=(x-4)/2
What is the inverse of the function y equals 5x-5?

In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
What is the inverse of the equation y equals 4x?
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
What is the inverse function of y equals 2x minus 4?
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.
What is the inverse to the statement x equals y?
x=y is the identity. It is its own inverse. So the inverse is y=x.
What is the multiplicative inverse of -4-y?
If y is equal to -4 there is not a multiplicative inverse. If y is different than -4 the inverse is: -1/(4+y)
What is the inverse of y equals 4x - 2?
y=x+2/4 (x+2 is all over four)
What is the inverse of y equals x?
The inverse of the function y = x is denoted as y = x. The inverse function essentially swaps the roles of x and y, so the inverse of y = x is x = y. In other words, the inverse function of y = x is the function x = y.
Which function is the inverse function of y 5x - 4?

Is x plus y equals 8 a inverse varition?
x+y=8 y=-x+8 is not an inverse variation. However, y=8/x is an inverse variation or y varies inversely as x.
What is the inverse of y equals 4x-2?
