What is the end behavior of the polynomial function?

1 answer:

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

Please help me with this problem. I am not sure if I am correct.

Answer:

only -7

Step-by-step explanation:

Just plug them in.

so for x=-7 $\sqrt{-2(-7)-5}=(-7)+4\\\sqrt{9}=-3 \\ 3=-3$ So this one is extraneous

Then if you plug -3 in you get 1 = 1 so this one is not extraneous. if you need me to work this one out let me know.

The perimeter of a rectangle is 150 cm. the length is 4 cm greater than the width find the width and length

Fudgin [204]

Let's call the width of our rectangle $w$ and the length $l$ . We can say $l = w + 4$ , since the length is equal to 4 cm greater than the width.

Also remember that the perimeter of a rectangle is the sum of two times the width and two times the length, or $P = 2l + 2w$ . To solve this problem, we can substitute in the information we know, as shown below:

$150 = 2(w + 4) + 2w$

$150 = 4w + 8$

$142 = 4w$

$w = \frac{71}{2}$

Now, we can substitute in the width we found into the formula for length, which is $l = w + 4$ :

$l = \frac{71}{2} + 4$

$l = \frac{79}{2}$

The width of our rectangle is $\boxed{\frac{71}{2} \,\, \textrm{cm}}$ cm and the length of our rectangle is $\boxed{\frac{79}{2} \,\, \textrm{cm}}$

Two friends, Vani and Shaquana, took summer jobs. The equation y=28.8xy=28.8x represents Vani's earnings in dollars and cents, y

An equation is formed of two equal expressions. Shaquana earns $10 less per hour than Vani.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation y=28.8x represents Vani's earnings in dollars and cents, y, for working x hours.

y = 28.8x

y/x = 28.8

Hence, Vani is paid $28.8 per hour.

The amount that Shaquana earned was $653.40 in 33 hours. Therefore, per hour she was paid

Amount per hour = $653.40/33 = $19.8 per hour

The difference between the two is,

Difference = $28.8 - $19.8 = $10

Hence, Shaquana earns $10 less per hour than Vani.
