4C- The squareroot graph
Objectives
Task 2: Investigating the reflection of the graph in x-y axis
Task 3: Investigating dilation factor from y-axis graphs
- identify the equation of the square root relation
- identify the dilation factor and the translation factors
- recognize the shape of the relation and its reflection in both x and y axis
- Exercise 4C: Q1,2
Task 1: Investigating the variables a,h,k
Play around with the variables and answer the following questions in your book
- Describe the graph graph when you increase and decrease 'a'
- Describe the graph graph when you change 'h' and 'k'
- what conclusion can you make about the coordinate (h,k) from the equation
Task 2: Investigating the reflection of the graph in x-y axis
Play around with the variables and answer the following questions in your book
- Describe the graph when 'a' is negative
- Describe the graph the graph when 'b' is negative
- Describe the graph when both 'a' and 'b' are negative
- Describe the graph when you change 'b'
Task 3: Investigating dilation factor from y-axis graphs
- Write the equation of this square root function using the variables given to you
- Using the equation, explain why the endpoint of the graph is at x=2 and y=2
Task 4: Copy the notes
