Which polynomial function f(x) has a leading coefficient of 1, roots –5, 3, and 6 with multiplicity 1, and root –2 with multiplicity 3? f(x) = 3(x + 2)(x + 5)(x – 3)(x – 6) f(x) = 3(x – 2)(x – 5)(x + 3)(x + 6) f(x) = (x + 2)(x + 2)(x + 2)(x + 5)(x – 3)(x – 6) f(x) = (x – 2)(x – 2)(x – 2)(x – 5)(x + 3)(x + 6)

Isabel graphed the following system of equations. 2x – y = 6 y = -3x + 4 she came up with the solution (2,-2). what were the 3 steps she did to get that solution? (make sure they are in the correct order)

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
