- Diapositiva: 1
- |x-h| + k
- f(x)=∣x−3∣+2Vertex: (3,2)
- Okay and how do you know whats the maximum or minimum of this equation, without having a graph
- I will later show you a graph where the axis of the symmetry, Vertex, and the minimum value are located
- Okay, so this equation has a minimum value because the function open upwards. In this case The minimum value is 2 because the vertex is (3,2) and 2 is the lowest point that Y can get.
- Diapositiva: 2
- ohhh, okay now I understand it.
- Okay, imagine we are in the sky, and I am going to explain the graph
- So the green line is the axis of symmetry and the red dot is the minimum value and vertex
- Diapositiva: 3
- f(x)=∣x−3∣+2Vertex: (3,2)
- |x-h| + k
- Thank you for all the information , but I wanted to know one more thing, what is the domain and range in this equation
- We are almost done and it's nearly time for the test, so basically the Domain and range in this equation are Domain= ARN and Range= Y is greater than or equal to 2
- The domain is ARN because it goes from negative infinite to positive infinite, and The range is Y greater than or equal to 2 because since the vertex is (3,2), the least value the absolute value function can get is 2
