Graphing Square Root Functions
-
y = √x
- Represents the principal square root function.
- Graph starts at the origin (0,0) and extends to the right in a curve.
- Only for non-negative values of x (x ≥ 0).
-
y = -√x
- Represents the negative square root function.
- Graph starts at the origin (0,0) and extends downward to the right.
- Only applicable for non-negative values of x (x ≥ 0), producing a reflection of y = √x across the x-axis.
-
y = -√-x
- Represents a transformation of the square root function with negative input.
- Graph starts at the x-axis moving leftward (for x ≤ 0).
- Reflects the negative square root function across the y-axis.
-
y = √-x
- Represents the positive square root function with negative input.
- Graph starts moving leftward from the origin (0,0), applicable for non-positive values of x (x ≤ 0).
- Produces a reflection of y = √x across the y-axis.
