The inverse of a cubic function is also a function. a. always true b. sometimes true c. never true a linear function has an inverse relation. a. always true b. sometimes true c. never true

b. sometimes true

If the derivative of the cubic has two real zeros, the inverse relation will not pass the verical line test.

_____

The attached graph shows two inverse cubic relations, one a function, one not.

y=mx+b

step-by-step explanation:

m slope, b y-intercept

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
