Which statement best describes the function below?

f(x)= x3 - x2-9x +9

It is a many-to-one function.

Step-by-step explanation:

it is a function because for every x values there is only one correspondent y value. Therefore it pass the vertical line test. So, option A and C are not correct. In the figure attached, a plot of the function can be seen. It is notice that different x values gives the same y value. In consequence, it is a many-to-one function. One-to-one functions are those in which every y value correspond to exactly one x value.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
