Answer:

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)

Step-by-step explanation:

The domain is the set of all x values in the function. The range is the set of all y values in the function. It is written in parenthesis from least to greatest. Do not repeat values even if the function has them more than once.

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!

To figure this out, use the acronym SOHCAHTOA to determine which trigonometric function to use.

8 is opposite to <R and 3 is adjacent to <R so we use tangent.

Set up the following equation: tan(x)=8/3

Find the inverse (aka. tan^-1): x=69.44

So your answer is <R=69.4 degrees

Hope this helped!

Find a power series for the function, centered at c. f(x) = 1 9 − x , c = 4 f(x) = [infinity] n = 0 Incorrect: Your answer is in

Wewaii [24]

Looks like the given function is

$f(x)=\dfrac1{9-x}$

Recall that for |x| < 1, we have

$\displaystyle\frac1{1-x}=\sum_{n=0}^\infty x^n$

We want the series to be centered around $x=4$ , so first we rearrange f(x) :

$\dfrac1{9-x}=\dfrac1{5-(x-4)}=\dfrac15\dfrac1{1-\frac{x-4}5}$

Then

$\dfrac1{9-x}=\displaystyle\frac15\sum_{n=0}^\infty\left(\frac{x-4}5\right)^n$

which converges for |(x - 4)/5| < 1, or -1 < x < 9.

The sum of 13 and twice a number is seven less than six times a number. what is the number

Trava [24]

Let, the number = x
It would be: 13 + 2x + 7 = 6x
2x+20 = 6x
6x-2x = 20
4x = 20
x = 20/4
x = 5

In short, Your Answer would be 5

Hope this helps!
