Quadratic Function Real World with Graphs

What is the output (y) called where x=0. It is the starting point for real world.

• y-intercept/initial value

• x-axis

• vertex

• line

• Function
• Not a Function

Let's dive into the math jungle! Can you identify which function family this belongs to?

• Linear

• Exponential

• Quadratic

• Cubic

Guess my family! Am I Linear, Quadratic, Exponential, or a Linear Absolute Value function?

• Linear

• Quadratic

• Exponential

• Linear Absolute Value

• The times at which the ball hits the ground

• The maximum height of the ball

• The initial height of the ball

• The speed of the ball

Looking at the graph,

The vertex is at Point ​ (a)  

The Positive Zero is at Point ​ (b)  

The y-intercept is at Point ​ (c)  

The Negative Zero is a Point ​ (d)  

• 3

• 4

• 2

• 1

• Not Shown
