To find the domain of a function using Khan Academy, follow these steps:Step 1: Identify the Function
The first step is to identify the function you want to find the domain for. For example, let’s use the function f(x) = √(x+2).Step 2: Determine the Restrictions
Next, determine any restrictions on the function. In our example function, the radicand (x+2) must be greater than or equal to zero to avoid imaginary numbers.Step 3: Write the Domain
Finally, write the domain using set notation. In our example, the domain would be D = {x | x ≥ -2}.Using Khan Academy to Find the Range
To find the range of a function using Khan Academy, follow these steps:Step 1: Graph the Function
The first step is to graph the function. Khan Academy has a graphing calculator tool that you can use for this step.Step 2: Look at the Y-Values
Next, look at the y-values (output values) of the function on the graph. Determine the highest and lowest y-values.Step 3: Write the Range
Finally, write the range using a set notation to include all possible y-values. For example, if the highest y-value is 5 and the lowest is -3, the range would be R = {y | -3 ≤ y ≤ 5}.Tips for Determining Domain and Range with Khan Academy
Tip 1: Pay Attention to Restrictions
When finding the domain of a function, be sure to pay attention to any restrictions. These may include square roots, denominators, or logarithms.Tip 2: Trust the Graph
