Tips and Hints

1.
What I know about transformations are that when there is a number with x eg. (x+3), the graph goes to the left. If you were to have something like (x-3) the graph would shift 3 units to the right. In the case of the number being outside the parentheses the graph would shift up or down depending on the problem.
Ex.
y=(x+1)-8....
This graph would shift 1 unit to the left and 8 units down.
The only helpful tip I can say about transformations is that if you want to determine if the graph goes to the left or right make the y=0 and just solve for the x and the number.
Like y=(3x+15)-39
0=(3x+15)
0=x+15 minus 15 to both sides
your left with x=-15
When the graph goes up or down that is easier, you just need to look at the positive and negative numbers.

2. Honestly, about trigonometry I can't remember much (I have a horrible memory), but I do remember somewhat of sin, cos, and tan, and there reciprocals. I remember the TRICKY unit circle which I didnt understand in my Trig class, but now in calculus I kearned how to remember the radians and the coordinates, (1/2 , root of 3/2) which is pi/3.
From my Trig class I don't remember much but I do remember some of the graphs...like a parabola, x^3 graph, I now remember how to do asymptotes on the tan graps(:
Other than that I really dont remember much but have learned in calculus all over(:

3. What worries me is inverse like how to find or solve for x. When there are a lot of other numbers in front of it, how to graph the inverses or the sohcahtoa graphs, the more complex graphs.
