​Solve by factoring:

​What are the solution(s)?

​Parallel, perpendicular, neither

​Write an equation that passes through the given point and is perpendicular to the given line.

​(0, -5); x - 6y = -2

​Now write an equation that is parallel to the given line and goes through the given point.

​(-3, 4); y = 2

​Key features of quadratic graphs

​1. Axis of symmetry, x = -b/2a; This is the x-value of the vertex. To find the y-value of the vertex, plug in this number for x into the function to solve for y.

2. Solution(s): x-intercepts (where y = 0), roots, zeroes

3. vertex - coordinate point that is the max or min of the function.

4. domain - the possible x-values for the function

5. range - the possible y-values for the function

6. end behavior - for left side, x → - ∞, what is the y → ∞ (increasing) or -∞ (decreasing). DO the same this for the right side where x → ∞.

7. increasing sections, decreasing sections - Write inequality using x. Ex. 0<x<4 -- Never use ≤, ≥
