Notice that the functions from previous examples were all polynomials, and their inverses were radical functions. If we want to find the inverse of a radical function, we will need to restrict the domain of the answer because the range of the original function is limited.

How To: Given a polynomial function, restrict the domain of a function that is not one-to-one and then find the inverse.

I may not need to graph this because the numerator and denominator of the rational expression are both linear.For any one-to-one function f ( x) = y, a function f − 1 ( x ) is an inverse function of f if f − 1 ( y) = x. This can also be written as f − 1 ( f ( x)) = x for all x in the domain of f. It also follows that f ( f − 1 ( x)) = x for all x in the domain of f − 1 if f − 1 is the inverse of f.

To find out the length of ladder needed, we can draw a right triangle as shown in Figure 1, and use the Pythagorean Theorem. Figure 1. a 2 + b 2 = c 2 5 2 + 12 2 = c 2 169 = c 2. Now, we need to find out the length that, when squared ...Graph Radical Functions. Before we graph any radical function, we first find the domain of the function. For the function, f ( x) = x, the index is even, and so the radicand must be greater than or equal to 0. This tells us the domain is x ≥ 0 and we write this in interval notation as [ 0, ∞). Previously we used point plotting to graph the ...Graph Radical Functions. Before we graph any radical function, we first find the domain of the function.
