Answer:

A. This is a function because every input maps to only one output.

D. Cubic Function

Step-by-step explanation:

For this mapping to be considered a function it must only have one y-value for each x value. This is the case, and this is what option A describes.

From its shape, we can see that D is a cubic function. Let's look at the shapes of each of the other functions just to be sure.

A. Linear Function

This graph would be a line.

B. Absolute Value Function

This graph would be in a "V" shape

C. Quadratic function

This graph would be in a "U". or parabolic shape

D. Cubic Function

This would have the same basic shape as the one in the graph.

Given : 11x – 6y = –1; x = 8

Natasha_Volkova [10]

Answer:

B. a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Symmetric Property of Equality

Step-by-step explanation:

Given expression,

$11x - 6y = -1; x = 8$

By substituting x = 8,

$11(8) - 6y = -1$

$88 - 6y =-1$

By subtraction property of equality,

$-6y = -89$

Division property of equality,

$y = \frac{89}{6}$

By symmetric property of equality,

$\frac{89}{6} = y$

A person trying to gain access to a bank vault must pass through a series of three security doors. If an attempt to pass through

ExtremeBDS [4]

Answer:

C) S = {F, PF, PPF, PPP}

Step-by-step explanation:

For this case, we know that a person is trying to gain access to a bank vault and needs to go through 3 security doors, and we know that if the person does not pass a door, then he/she has no other attempts. We denote P= Successful pass , F= Failed pass

And we are interested on the sample space, we need to remember that the sample is the set with all the possible values for an experiment.

For this case the person can fail at the 1,2 or 3 try

For the case that fails at the 1 try we have F

For the case that fails at the 2 try we have PF

For the case that fails at the 3 try we have PPF

And the last option is that the person not fails at any try and we have PPP

So then the sample space would be given by:

C) S = {F, PF, PPF, PPP}
