A) as x decreases within bound, f(x) increases without bound.

b) as x decreases without bound, f(x) approaches zero

c) as x increases without bound, f(x) approaches the line y = - 4

d) as x decreases without bound, f(x) approaches the line y = - 4

a) As x decreases within bound, f(x) increases without bound.  

c) as x increases without bound,f(x) approaches the line y = - 4

Step-by-step explanation:

From the graph, we can see, as x becomes more negative, y gets larger and larger.  

As x→ -∞, y → ∞

As x decreases without bound, y increases without bound

We can also see as x gets larger and larger, y gets closer to -4

As x →∞, y → -4

As x increases without bound, y approaches -4

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".

may i see the picture? it would a lot, xox
