Let v = (8, -4) and w = (-4,2).

which of the following is true?
check all that apply. (30 pts)

a. v x w = 40
b. the y-component of w is 2.
c. v = -2w
d. the x-component of v is 4.

The second value in a set of parenthesis is the y value, so B is true.

If you multiplied each value of W by -2, you would get the values for V, so C is also true.

The answer is B and C.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
