Final answer:
The subject of this question is mathematics, and the topic is curve defined by parametric equations calculator. The correct option is Quadratic regression.
Step-by-step explanation:
The subject of this question is mathematics. The topic being asked about is curve defined by parametric equations calculator. The correct option from the given choices is D) Quadratic regression.
To use a quadratic regression calculator to define a curve, you would input the data points into the calculator and use a regression function to find the quadratic equation that best fits the data. This equation can then be used to graph the curve.
For example, if you have a set of data points (x, y), you can enter these points into the calculator and find the equation of the quadratic curve that best fits the data. This equation can then be used to graph the curve and analyze its properties.
