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.

Consider a graph for the equation y= -3x+4. What is the y intercept?
Alexeev081 [22]

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 4 is in this form

with y- intercept c = 4 → A

An experiment was conducted to test the effect of a new cholesterol medicine. Fifteen people were treated with medicine X and 15
gtnhenbr [62]

Considering the hypothesis tested and the p-value of the test, the correct option is given by:

There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if there is no difference between the cholesterol levels, that is:

H₀:Hₓ-H

At the alternative hypothesis it is tested if there is a difference, hence:

H₀:Hₓ-H≠0

The p-value is of 0.003 < 0.01, hence we reject the null hypothesis and conclude that there has was a difference, hence the correct option is given by:

There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.
