I need help understanding domain and range, I don't know what I am trying to solve when asked to find the domain and range of an equation. Other terms that are used are function, input and output values. I need help understanding all of these terms please. Some example equations from the lesson are F(x)= 2x+3 and h(y)=3/4-y. Is anyone able to walk me through these problems step by step as the lesson does not do so. Thanks.
