Christine, 4.5 introduction to Functions

Today in class, we started learning about functions! At first, we all thought that it would be super confusing! But when looking into the chapter, it makes a lot of sense. We use a lot of information we learned in past chapters. We did a digital scavenger hunt on google docs which helped us understand functions. I feel like I am starting to really understand math and especially functions. I thought that it was really cool that x and y values are also known as domain and range. At first, I really didn't understand the what a function was, but the definition in the book made it very clear to me. A function is a relation in which, for each value of the first component of the ordered pairs, there is exactly one value of the second component.

Sorry the pictures of graphs wouldn't upload but I will post them later!
