Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

@ngmvpelite You definitely don't have to graph them. Just set them equal to each other to find the points where they intersect each other, and then do exactly what you suggested, which is to pick a value between the intersection points, plug it into both functions, and see which one is higher. You got it! :)

Today I finish my Calculus 1 course. All I need to get an A in the class is a 73% on the final, because I have done so well on the tests. Your videos helped me a lot this semester, and I can't wait to learn more from you in Calc 2 this summer. I hope you have a lovely day, and God Bless you! :)

@SuCKeRPunCH187 Sorry, I didn't mean range as in range vs. domain. I should have used a different word. I just mean the area between x=1 and x=7. :)
