Today we continued working with absolute value functions. Ben has shown mastery in the ability to graph the function. We reviewed what makes the function stretch, shrink, and reflect. Then we considered the domain and range. Ben now knows the domain of abs. value functions is all real numbers. Next we determined the range is either all positive numbers or all negative numbers. I asked Ben how we can tell if the range would be positive or negative, and with some help, he was able to determine that if the leading term is positive, the range would be positive and if the leading term is negative the range would be negative.
