∙ 12y agoy = 5x - 4
y + 4 = 5x
x = (y + 4)/5
Conventionally, the x and y are then swapped in the expression of the inverse function.
So, the inverse function is y = (x + 4)/5

How do you complete the inverse of fx?
Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3
What is an inverse function?
A function that, given X, will produce Y has an inverse function that will take Y and produce X. More formally:If f(x)=y, then f-1(y)=xWhere f-1() denotes the inverse function of f()
Is the inverse of a linear function not a function?
The inverse of a linear function is always a linear function. There are a few ways to approach this.To think about it, you can imagine flipping the x and y axes. Essentially this equates to turning the graph of the linear function on its side to reveal the new inverse function which is still a straight line.More rigorously, the linear function y = ax + b has the inverse equation x = (1/a)y - (b/a). This is a linear function in y.
Inverse of 9x-?
The inverse of the function y = 9x is x/9.
Example of a function that has no inverse function?
y = sin x is such a function. It has an inverse, of course; but the inverse, sin-1, strictly speaking, is not a function.Example: Given that x = pi/6, y must equal 0.5. However, given that y = 0.5, x can equal pi/6, 5 pi/6, 13 pi/6, 17 pi/6, or an infinity of values, both positive and negative.For y to be a function of x, and x to be, also, a function of y, there must be exactly one value of y that answers to a given value of x, and vice-versa. Then, and only then, is each function the inverse of the other.
What is the inverse function for f(x)5x-20?
To find the inverse of a function, you have to switch y for x and then solve for y again. These are the steps: y = 5x - 20 x = 5y - 20 5y = x + 20 y = 0.2x + 4 or f(x)^-1 = 0.2x + 4
What is the inverse of the equation y 5x - 1?
y = 5x + 1 y - 1 = 5x (y - 1) / 5 = x
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 difference between a reciprocal function and an inverse function?
A reciprocal function will flip the original function (reciprocal of 3/5 is 5/3). An inverse function will change the x's and y's of the original function (the inverse of x<4,y>8 is y<4, x>8). Whenever a function is reflected over the line y=x, the result is the inverse of that function. The y=x line starts at the origin (0,0) and has a positive slope of one. All an inverse does is flip the domain and range.

Is 5x plus 4y equals 0 a function?
Yes it is a function. 5x + 4y = 0 the same as: 5x = -4y You can also solve for either variable. x = - ( 4 / 5 ) y y = - ( 5 / 4 ) x
What is inverse of a function?
Simply stated, the inverse of a function is a function where the variables are reversed. If you have a function f(x) = y, the inverse is denoted as f-1(y) = x. Examples: y=x+3 Inverse is x=y+3, or y=x-3 y=2x+5 Inverse is x=2y+5, or y=(x-5)/2
How do you complete the inverse of fx?
Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3
Suppose you graph y equals 5x - 4 Which function can you graph to increase the y-intercept by 6 but leave the slope unchanged?
y = 5x + 2

Inverse function 2x plus 4?
y=2x+4 --> x=2y+4 ==> y=(x-4)/2
What is the inverse of yx5 x4 x?
Put simply, the inverse of y=x^5+x^4+x is x=y^5+y^4+y. Unfortunately, this is a quintic function and there is no quintic formula.
