What key graphical features are obtained from a polynomial function?

1 answer:

7 0

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

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

</span><span>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.

</span><span>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.

A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going

AleksAgata [21]

Answer:

200.96 feet

Step-by-step explanation:

We have a pool with a radius of 28 feet.

They also tell us that there is a path around the pool and its width is 4 feet.

Thus:

The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.

= (28 + 4) feet

= 32 feet

To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.

The circumference of the outer edge of the pool path would be equal to the perimeter.

p = 2 * pi * r

replacing

p = 2 * 3.14 * 32

p = 200.96 feet

therefore 200.96 feet are needed

Which expression is equivalent to 7x , if b > 0?

AlladinOne [14]

<h3>Answer: Choice C</h3>

Work Shown:

$7x^2*\sqrt{2x^4}*6\sqrt{2x^{12}}\\\\7*6x^2*\sqrt{2x^4*2x^{12}}\\\\42x^2*\sqrt{4x^{4+12}}\\\\42x^2*\sqrt{4x^{16}}\\\\42x^2*\sqrt{(2x^8)^2}\\\\42x^2*(2x^8)\\\\42*2x^{2+8}\\\\84x^{10}\\\\$

So that's why the answer is choice C

The requirement that x is nonzero isn't technically necessary. The original expression simplifies to choice C even when x = 0 is the case. Also, we don't have issues such as division by zero errors that could arise. It's a bit curious why your teacher put in that condition.
