Answer:

b is the correct answer.

Step-by-step explanation:

Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.

Answer:

A) y=19x-810

Step-by-step explanation:

This line of best fit is moving downward, or negative. The last number in the equation represents where the line intercepts the y axis, hense the y-intercept. Which is 810.

Now there are only two equations in which 810 is last in the equation. And B) would have the line moving upward, so A is the answer.

Hope this helps!

Graph the following piecewise function.

atroni [7]

Answer:

The graph of this piece-wise function is attached below.

Step-by-step explanation:

Given the function

${\displaystyle f(x)={\begin{cases}x^{2} +2&{\text{if }}-5\leq x$

A piece-wise function is a function which has multiple pieces.
Each of the pieces have their own restrictions.

The domain of a function is the set of input, or x, values for which the function is defined.
The range is the set of all values taken by the function

As the piece

$f(x)=x^{2} +2$ has the domain [-5, 3) and graph of this piece is attached below.

and

$f(x)=x-4$ has the domain [3, 7) and graph of this piece is attached below.

So, the domain of the piece-wise function can be composed as [-5, 3) U [3, 7) and range has the interval $\:\left[-1,\:27\right]$ .

i.e.

Domain: [-5, 3) U [3, 7)

Range: $\:\left[-1,\:27\right]$

The graph of this piece-wise function is attached below.
