In order for a fourth degree function to have an inverse function, its domain must be restricted. Otherwise the inverse function will not pass the vertical-line test.Ex.f(x) = x^4 (x>0), the original functionf-1(x) = x ^ (1/4), the inverse

if f(x) = 4x, then the inverse function g(x) = x/4

The inverse of the inverse is the original function, so that the product of the two functions is equivalent to the identity function on the appropriate domain. The domain of a function is the range of the inverse function. The range of a function is the domain of the inverse function.

No. The inverse of an exponential function is a logarithmic function.

-6 is a number, not a function and so there is not an inverse function.

The inverse of the cubic function is the cube root function.

1. its -4 over x

The original function's RANGE becomes the inverse function's domain.

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.

X squared is not an inverse function; it is a quadratic function.

The inverse function means the opposite calculation. The inverse function of "add 6" would be "subtract 6".

Range

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.

No. A simple example of this is y = x2; the inverse is x = y2, which is not a function.

If the quadratic function is f(x) = ax^2 + bx + c then its inverse isf'(x) = [-b + +/- sqrt{b^2 - 4*(c - x)}]/(2a)

The inverse of the cosine is the secant.

It is the logarithmic function.

it is 1 divided by the function

No, an function only contains a certain amount of vertices; leaving a logarithmic function to NOT be the inverse of an exponential function.

No.Some functions have no inverse.

The inverse for f(x) = 4x + 8 isg(x) = x/4 - 2

The opposite of another function - if you apply a function and then its inverse, you should get the original number back. For example, the inverse of squaring a positive number is taking the square root.
