for this blof i will go over section 3. i finally figured out how to do this part and now i find it very easy and hopefully i can keep figuring out how to do all the other stuff so i can pass the test. there are only a few formulas to follow and they are very easy.
1.) Y-axis - You have to plug in (-x)
2.) X-axis - You have to plug in (-y), then simplifiy; if the equations are equal then it has symmetry.
3.) Origin - You have to plug in (-x) and (-y)
4.) Y=X - You have to switch x and y, and then solve for y.
Section 4-1 dealt with domain and range, and finding the zeros. this was also a easy part that i found in chapter 4 and hopefully the written part has alot of these so i can pass that one too.
ex.
y=4x^2+6x-7
D:(-∞,∞)
R:
Zeros:(x+7)(x-1)
x=-7,1
