Stanley analyzes the table of values for a polynomial function. he has determined through applying descartes rule of sign there is 1 negative real zero, and either 1 or 3 positive real zeros. he has also determined that the upper bound of the function is 3.
what is the degree of the polynomial function? how can you tell? how many positive real zeros does the function have? how can you tell?

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
