The coordinates of the vertices of ABC are A(1, 2), B(7, 3), and C(4, 8). If A’ is (−1, −2) after a rotation of 90 about the point (2, −1). State the coordinates of B' and C', after the same rotation.

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

ab will be equal to

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
