Use the leading coefficient test to determine the end behavior of the polynomial function?

1 answer:

8 0

This is a parabolic function
A negative lead coefficient means that f(x) is increasing from the left and decreasing to the right. It will have a maximum value vertex.

Answer:

30 SQUARE units

The slope is 35. The y-intercept is 550. what can you conclude?

MrRa [10]

Answer:

the formula is y = mx + b. (m) represents slope and (b) represents the intercept

Step-by-step explanation:

So with that formula and info given, you can form the equation y = 35x + 550

Prove that if r is any rational number, then 3r2 − 2r + 4 is rational. The following properties may be used in your proof. Prope

ziro4ka [17]

Given:

Expression is

$3r^2-2r+4$

To prove:

If r is any rational number, then $3r^2-2r+4$ is rational.

Step-by-step explanation:

Property 1: Every integer is a rational number. It is Theorem 4.3.1.

Property 2: The sum of any two rational numbers is rational. It is Theorem 4.3.2.

Property 3: The product of any two rational numbers is rational. It is Exercise 15 in Section 4.3.

Let r be any rational number.

We have,

$3r^2-2r+4$

It can be written as

$3(r\times r)-2r+4$

Now,

3, -2 and 4 are rational numbers by property 1.

$r^2=r\times r$ is rational by Property 3.

$3r^2\text{ and }-2r$ are rational by Property 3.

$3r^2+(-2r)+4$ is rational by property 2.

So, $3r^2-2r+4$ is rational.

Hence proved.
