Thanks for the help!

NikAS [45]

Answer:

Step-by-step explanation:

So we have the piecewise function:

$f(x)= \begin{cases}\sqrt{2x} & \text{if }x$

And we want to find f(8).

Since our input value is 8, choose the equation that fits our input.

The first equation demand x to be less than 3. 8 is not less than 3, so we won't use that.

The second equation demand x to e greater than or equal to 3 and less than 8. 8 is <em>not</em> less than 8. So, we won't use that.

The third equation demands x to be greater than or equal to 8. 8 is greater than or equal to 8, so we'll use the third equation.

So:

$f(x)=42\text{ if }x\geq 8$

$f(8)=42$

There're nothing more to do, we're done :)

The answer is A.

Write an input and output pair that is a function and stays a function when you switch the input and output

strojnjashka [21]

9514 1404 393

Answer:

{(1, 2), (3, 4)}

Step-by-step explanation:

If you want both the relation and its inverse to be functions, there can be no repeated x-values, and no repeated y-values.

In the above pair of points, I have avoided duplicates by making all of the values different. That is not necessary, but it satisfies this problem easily.
