Determine the domain and range of the given function.

The domain is all real numbers

The range is all real numbers greater than or equal to

Step-by-step explanation:

we know that

The function in the figure is a vertical parabola

The vertex of the function is the point

The parabola open upward------> the vertex is a minimum

The domain is the interval------> (-∞,∞)

The domain is all real numbers

The range is the interval------> [-2,∞)

The range is all real numbers greater than or equal to

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
