Which statement correctly describes the end behavior of f(x)=−9x4+3x3+3x2−1?

As x→∞, f(x)→∞, and as x→−∞, f(x)→−∞.
As x→∞, f(x)→−∞, and as x→−∞, f(x)→−∞.
As x→∞, f(x)→−∞, and as x→−∞, f(x)→∞.
As x→∞, f(x)→∞, and as x→−∞, f(x)→∞.

The second option, "As x→∞, f(x)→−∞, and as x→−∞, f(x)→−∞."

Step-by-step explanation:

Both end behaviors trend toward negative infinity! I recommend graphing on a calculator (or just by googling the equation) to see what it looks like :)

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
