What key graphical features are obtained from a polynomial function?

1 answer:

7 0

The key graphical features obtained from a polynomial function are: the zeros, the turning points and the end behaviour.

A "zero" of a polynomial function is an input value that produces an output of zero (0).

A turning point is a point of the graph where the graph changes from increasing to decreasing or decreasing to increasing. A polynomial of degree n will have at most n – 1 turning points.

The end behavior of a polynomial function is the behavior of the graph of f as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.

Step-by-step explanation:

f(x) = sqrt(x)

A reflection over the x axis is-f(x)

g(x) = -sqrt(x)

x -sqrt(x)

Sadie is 3 years older than Kareem, and Kareem is twice as old as Nadra. The sum of their ages is 33.

Dima020 [189]

Answer:

Step 1-Write an equation, letting x represent Kareem’s age:

(x + 3) + x + 2 x = 33

Step 2-Solve the equation:

(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.

Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.

Which corrects the student’s first error?

1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.

2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.

3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.

4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.

used to flavor vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest amount. Th

lubasha [3.4K]

Answer:

The cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 5.95 x 10^7 ft^3 is $ 0.07.

Step-by-step explanation:

The volume of the hangar is

$V=5.95*10^7 \, ft^3$

The minimal amount of vainilla needed to be detected in the hangar is equivalent to the threshold multiplied by the volume of the hangar:

$Va=V*Th=5.95*10^7 \, ft^3*2.0*10^{-11}\,\frac{g}{L}*\frac{28.317L}{1ft^3}\\ \\Va=336.9723*10^{-4} \, g=0.0337\,g$

The cost of this amount of vainilla is

$Cost = Va*p=0.0337\,g*\frac{104\, usd}{50\, g} =0.07 \, usd$

The cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 5.95 x 10^7 ft^3 is $ 0.07.
