What set describes the zeroes of the function f(x )= 6πsin(4x) shown in the graph?

" for every integer "

Step-by-step explanation:

The function has zeroes at the x-intercepts in the graph.

If you look at the graph from 0 to , you will see that the graph cuts the x-axis at 4 points.

They are at half of , which is , at , at half point between and , which is at , and at .

They are basically all multiples of .

Looking at the answer choices, the third choice is correct.

Plugging in k=1, k=2, k=3, and k=4 into the equation, we see that the zeroes are exactly what we saw. Also, the negative side of the function holds true as well.

Third answer choice is right.

explanation:

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".
