Which of the following graphs represents a function help ASAP!!!

1 answer:

4 0

To be a function, there needs to be only y for one x. So if the curve comes back on itself and you have, for example two answers for the same x it's not a function.
In this case, the only one is the last one.

Match each of the trigonometric expressions below with the equivalent non-trigonometric function from the following list. Enter

Answer:

Step-by-step explanation:

In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.

It should be clear that

$tan(sin^{-1} x/4) = x/\sqrt{16-x^{2} }$

$sin(tan^{-1} x/4) = x/\sqrt{16+x^{2} }$

sin(2α) = 2 sinα cosα

So,

$1/2 sin(2sin^{-1} x/4) = (1/2)(x/4) * x/\sqrt{16-x^2} = x^{2} /(8\sqrt{16-x^2})$

See what you can do with the others.

Can you please help me

Answer:

Step-by-step explanation:

Hi there!

To answer this, we must set it up as

$3x(2x^4-12x^2+7)$

Now we just use the distributive property to solve.

this becomes $6x^5-36x^3+21x$

I hope this helps!

Rewrite 3/9 as a mixed number

3/9 is already a fraction, you do not need to change it. 3/9 is not more than 9/9
