Elanso [62]

Answer:

a. p(n) is a function of n

b. p(2)=12.50

c. {0, 1, 2, 3, 4}

Step-by-step explanation:

A function is a rule or equation the p(n) depends on the variable n. We write it as p(n) is a function of n. It can also be written in symbols using p(input)=output for (input,output). We write p(2)=12.50. Lastly, every function has a domain which consists of input values or n values used. Here it is 0, 1, 2, 3, 4.

You start at (3, -3). You move down 1 unit and left 2 units. Where do you end?
Maslowich

Your end position is 1, -4)

<h3>How to determine your end position?</h3>

The start position is given as

Start = (3, -3)

The movement can be represented using the following translation rule

(x, y) = (x - 2, y - 1)

When the above translation rule is applied, we have:

End = (3 - 2, -3 - 1)

Evaluate the difference

End = (1, -4)

Hence, your end position is 1, -4)
