question
Which second degree polynomial function has a leading coefficient of -1 and root 4 with multiplicity 2?
f(x) = -x2 - 8x - 16
f(x) = -x2 + 8x - 16
f(x) = -x2 - 8x + 16
f(x) = -x2 + 8x + 16
answer
B)f(x) = -x2 + 8x - 16
question
Which polynomial function has a leading coefficient of 3 and roots -4, i, and 2, all with multiplicity 1?
f(x) = 3(x + 4)(x - i)(x - 2)
f(x) = (x - 3)(x + 4)(x - i)(x - 2)
f(x) = (x - 3)(x + 4)(x - i)(x + i)(x - 2)
f(x) = 3(x + 4)(x - i)(x + i)(x - 2)
answer
D) f(x) = 3(x + 4)(x - i)(x + i)(x - 2)
question
Which polynomial function could be represented by the graph below?
mc021-1.jpg
f(x) = x3 + x2 - 6x
f(x) = x3 - x2 - 6x
f(x) = -2x3 - 2x2 + 12x
f(x) = -2x3 + 2x2 + 12x
answer
C) f(x) = -2x3 - 2x2 + 12x
question

mc002-4.jpg
mc002-5.jpg
answer
C) mc002-4.jpg) 3-root11
question
