Graph y = 3x^2+2 a. what is the domain? b. what is the range? its been a long night

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

Given two triangles mno and xyz   with < m-=< x, < n-=< y and yo-=nz. the triangles are deduced to be congruent by aas (angle-angle-side) postulate which states that if there exists two corresponding angles and at least one side which is corresponding to a set of a given figure, then the figures are congruent.
therefore we can conclude that mno and xyz are congruent by aas
