Square Root Function (Graph)
The square root function, denoted by f(x) = √x, is a mathematical function that calculates the non-negative square root of a given input
The square root function, denoted by f(x) = √x, is a mathematical function that calculates the non-negative square root of a given input. It is a specific type of radical function.
The graph of the square root function is a curve that starts at the origin (0,0) and continues infinitely upwards in the first quadrant. It has a shape that resembles the right half of a sideways-opening parabola, with the vertex at (0,0) and the curve getting steeper as it moves away from the origin.
The main characteristics of the graph of the square root function are as follows:
1. Domain: The domain of the square root function is the set of all non-negative real numbers, since the square root of a negative number is undefined.
2. Range: The range of the square root function is also the set of all non-negative real numbers. This means that the outputs of the function can only be zero or positive values.
3. x-intercept: The x-intercept of the square root function occurs when the output (y-value) is zero. This happens only when the input (x-value) is also zero. So, the graph intersects the x-axis at the point (0,0).
4. y-intercept: The y-intercept of the square root function occurs when the input (x-value) is zero. The output (y-value) in this case is also zero. Therefore, the graph intersects the y-axis at the point (0,0).
5. Increasing Function: The square root function is monotonically increasing, meaning that as the input increases, the output also increases. However, as the input approaches infinity, the rate of increase slows down.
6. Symmetry: The graph of the square root function is symmetric with respect to the y-axis. This means that for any point (x, y) on the graph, the point (-x, y) is also on the graph.
7. Transformations: The graph of the square root function can be shifted vertically or horizontally by adding or subtracting constant values inside the square root function. Multiplying the entire function by a constant value scales the graph vertically.
Understanding the characteristics and graph of the square root function is essential in various mathematical fields, such as algebra, calculus, and geometry.
