what is the domain of this quadratic function? {x|x ≤ 2} {x|x ≥ 3} {x|3 ≤ x ≤ 7} all real numbers
what is the domain of this quadratic function? {x|x ≤ 2} {x|x ≥ 3} {x|3 ≤ x ≤ 7} all real numbers
Answer
Explanation:
Step1: Recall domain definition
The domain of a function is the set of all possible input - values (x - values).
Step2: Analyze quadratic function graph
For a quadratic function, as seen in the graph, there are no restrictions on the x - values. The graph extends infinitely to the left and right.
Answer:
all real numbers
