Another day with relations and functions. But mainly today we worked on equations and substituting in the variables. It's kind of hard for me to explain so I'll just show you.
EX:
f(x) = 4x2 - 2(x) + 5
f(4)
So all we had to do was replace all the "x's" with a four and solve it. So if you do the math correctly, the answer is 61.Just when I think I got the hang of it...the negatives come. Its still confusing my mind. I hate it so much that if i ever see it, I just skip it. Who wants to be a negative anyway? Positive is the way to go!
