Question

S What is the domain of the partial parabola? What is the domain of the line given?​

Answer 1

• The domain of a parabola is always all real numbers (sometimes written ( − ∞ , ∞ ) or x ∈ R ).
• To determine the domain, identify the set of all the x-coordinates on the function's graph. To determine the range, identify the set of all y-coordinates. In addition, ask yourself what are the greatest/least x- and y-values. These values will be your boundary numbers.
• The values of a, b, and c determine the shape and position of the parabola. The domain of a function is the set of all real values of x that will give real values for y. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.
• The straight line indicates that the relation is continuous. The straight line also indicates that all numbers are included in the domain and in the range. The domain and the range can be written in interval notation. Another name for interval notation is set notation.
