Question

1. which graph represents a function with a domain of all real numbers greater than or equal to - 7 and less than 2? 2. a quadratic function is graphed on the grid. which answer choice best represents the domain and range of the function? a domain: x≥ - 3 range: y > 5 b domain: all real numbers range: y≥5 c domain: x≥ - 3 range: all real numbers d domain: y≥5 range: x≥ - 1

Explanation:

Step1: Recall domain and range definitions

Domain is set of all x - values, range is set of all y - values.

Step2: Analyze the quadratic function graph

The graph of a quadratic function extends infinitely left and right for x - values (all real numbers for domain). The lowest y - value is 5 and it extends upwards, so range is $y\geq5$.

Answer:

B. Domain: All real numbers, Range: $y\geq5$
