To solve this problem you must keep on mind the following:
1.You have the following function:
y=3x^2+2
2. You can graph it by giving values to the variable x. Then, you must plot each point obtained.
3. When you plot each point, you obtain the graph shown attached, which is a parabola.
4. Therefore, you have the folllowing answers:
a. What is the domain?
The domain is:
All real numbers (R).
b. What is the range?
The range is:
y∈R:y≥2
