Lesson 1.2 -- Transformations

• How do you know if the graph is reflected over the x-axis?

• How do you know if the graph is vertically compressed? Vertically stretched?

• How do you know if the graph is shifted horizontally? (Left or Rt)

• How do you know if the graph is shifted vertically? (Up or Down)

If there was 1 food item you had to eat everyday for the rest of your life, what would it be?

Lesson 1.1 -- Key Features & ARoC

• Where is the graph increasing or decreasing?

• What is the graph's domain and range?

• Where is the graph positive or negative?

• Remember...only use y-values for the range! Everything else, look at the x-axis.

Lesson 1.1 -- Key Features & ARoC

• Do you remember the ARoC formula?

•  $ARoC=\frac{f\left(b\right)-f\left(a\right)}{b-a}$  

• What does it mean if the ARoC is negative?

• What does it mean if the ARoC is positive?

Lesson 1.5 & 1.6 --Solving a System of Equations & Inequalities

• You can have 1 solution, 2 solutions, No solutions or Infinite solutions.

• Remember that inequalities involve an interval solution or shading.

• Remember that equations involve a point or points of intersection.

• No intersection = No solution.

• If solving a system of equations algebraically, you may use the elimination or substitution method.
