FC: A YEAR IN REVIEW | MATH IS FUN | Cody Wood

1: GRAPHING | x-intercept (a,0) let y=0 and solve for x y-intercept (0,a) let x=0 and solve for y

2: Equations of lines | Parallel lines have equal slopes Perpendicular lines have negative reciprocal slopes Parallel- y=3x+1 y=3x+5 Perpendicular- y=3x+1 y=-1/3x+2

3: "The friends we meet on the path of life make the trip worth while." | Symmetry and Transformations | Reflections- opposite x same y (4,2) (-4,2) same x opposite y (4,2) (-4,2) Symmetry with respect to: x-axis (x,y) (x,-y) y-axis (x,y) (-x,y) origin (x,y) (-x,-y)

4: Direct Variation y=kx Inverse Variation y=k/x Joint Variation y=kxz k=constant | Variations

5: Quadratic Functions | Quadratic formula-x=(-b+/-square root of(b^2-4ac))/(2a) Discriminant- what is under square root

6: 2.4x^3+5x^2-x+2 Leading Term- first term-2.4x^3 Leading Coefficient-2.4 Degree-highest exponent 3 Cubic | Polynomial Functions

7: When adding or subtracting matrices the dimensions must be the same. When multiplying matrices, the columns(up and down) in the first matrix must equal the rows(left and right) in the second. | Matrices

8: Parametric Equations | x=t y=t^2 t is the parameter
