Square Root Functions

Objectives I can graph square root functions using transformations without a calculator I can determine the equation of a square root function from its graph. I can determine domain and range in Interval Notation from a graph

Square Root What are critical points Xy

Graph: y =

Pattern of Square Root

Domain and Range Domain: All x-Values that make up a graph or relation Range: All y-Values that make up a graph or relation REMEMBER: Interval Notation

Domain/Range of SQ Rt Domain: [0, ∞) Range: [0, ∞)

Domain & Range What’s under the radical determines starting point of the DOMAIN What’s after the radical determines starting point of the RANGE

Domain & Range Domain: [-1, ∞) Range: [3, ∞)

Domain: [0, ∞) Range: (-∞, 0]

Domain: [-3, ∞) Range: [3, ∞)
