the red fully circle in -1 show that -1 is include
Answer:
D) Quadratic
Step-by-step explanation:
A function is graphed on a coordinate grid.
- As the domain values approach infinity, the range values approach infinity.
Domain: If
then
Range:
- As the domain values negative infinity, the range values approach infinity.
Domain: If
then
Range:
We need to choose correct option which follows given domain and range.
Only quadratic function will follow the rule because it has even degree polynomial.
Quadratic function:
Degree = 2 and leading coefficient is positive.
Domain: 
Range: 
Hence, D is correct option.
