Determine the intervals of the domain over which each function is continuous. See Example 1.

Hello everyone. Using the following graph, we will write the domain for which the function is continuous. Then present the domain in interval notation. Our graph is a curve that passes through the X axis at the 0.20 20 is included in the graph. It is not a hole in the graph. We have four answer choices, all of which are slightly different intervals. Recall the domain means we're talking about the X values. I'm going to look at my graph and consider if there's any breaks where the X value does not exist, the only point that is labeled is the 0.0.20, but that is included in the graph. So this means there are no breaks and that our domain will be all real numbers which is answer choice a from negative infinity to positive infinity. Have a nice day.
