Today we only had a short class period because of the guest speaker. We started off class with a daily quiz on plotting lines. after we took the quiz, Jojo set the rest of the time aside to go over the last few nights of homework and any challenging problems.
For example, we went over problem 27 from our homework. it as a parabola, and we needed to find the domain and range. the problem was y= x(squared)-20. we know from plotting the parabola that the domain (the values of x)= (infinite, infinite). and since we know that the parabola will not go below the y-intersextion (which is -20) the range= [-20, infinite).
after we went over problems class was over. so YEAH!!! :D
tomorrow's scribe is christian.
