Example 2. Solve for x:(x + 3)4 = 16.Solution. To do that, we must first extract the argument, x + 3. To extract the argument of any function, simply take its inverse. In this example, take the 4th root of both sides of the equation. We can write immediately...

Here we have the function f(x) = 2x+3, written as a flow diagram:The Inverse Function goes the other way:So the inverse of: 2x+3 is: (y−3)/2The inverse is usually shown by putting a little "-1" after the function name, like this:f-1(y)...
A function ff is one-to-one if and only if every horizontal line intersects the graph of ff no more than once. Figure 2. (a) The function f(x)=x2f(x)=x2 is not one-to-one because it fails the horizontal line test. (b) The function f(x)=x3f(x)=x3 is one-to-one because...

The article discusses a mathematical equation on inverse matrix in Great Britain. It is stated that when matrices are added together, corresponding elements should also be added. It is noted that the matrix multiplication should be solved through...
Which is the correct inverse of the one-to-one function: {eq}\displaystyle f(x)=\frac{3x-1}{x+2} \\ \displaystyle (a)f^{-1}(x)=-\frac{2x-1}{x-3}, x \neq 3 \\ \displaystyle (b)f^{-1}(x)=\...

The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
