how to find domain and range of a function The range of a function is the set of all possible outputs eq y eq We will use these steps and definitions to find the intercepts asymptotes domain and range from the graph of a rational
Steps to Finding the Domain Step 1 Set the inequality to 0 instead of y or f x Step 2 Factor the polynomial completely then set each factor equal to zero to find the x intercepts zeros of Step 1 Find the domain To find the domain of a radical function you will set your radicand to the inequality 0 and solve for x Thus you will have a x b 0 Step 2 Find the range To

Step 3 Start at the bottom of the graph Find the range of each of the individual curves that make up the piecewise function Use the union symbol to join the ranges of the individual curves The domain of a function is the set of all input values that the function is defined upon It is all of the values that can be substituted plugged in to the function itself such that the
Finding the Domain Range from the Graph of a Continuous Function Step 1 To find the domain of the function look at the graph and determine the largest interval of x values for which there Finding the Domain and Range from the Graph of a Quadratic Function Step 1 Find the domain by examining the graph from left to right The domain includes all eq x eq values that are
