3. The vertices of a triangle are as follows:
(4,4), (6, 7), and (8,0)
If you dilate the triangle by a scale factor of 3, what are the vertices of the new triangle?

(12, 4), (18, 7), (24,0)
(12, 12), (18, 21), (24,0)
(12, 12), (6, 7), (24, 3)
(4, 12), (6, 21), (8,0)

(12,12), (18,21), and (24,0)

Step-by-step explanation:

You would multiple all the values by 3 so the vertices would become

(4*3,4*3),(6*3,7*3),(8*3,0*3)

(12,12), (18,21), and (24,0)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
