How do you determine if a set of ordered pairs is a function or not?

Answers

You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function! Watch this tutorial to see how you can determine if a relation is a function.
A function is a set of ordered pairs in which no 2 pairs with the same first element have a different second element. 

If you think about it, it makes sense. Think about  f(x) = x + 1. The pairs (x, f(x)) look like (1,2), (2,3), (3,4), (4,5), etc. If you also had (1,3) in the set, then there'd be two different answers for 1+1. The same applies to any function. There can only be one result for a given input value. Your welcome!!

The library at a certain university reported that journal prices had increased by 130% over a period of 10 years. The report concluded that this represented a price increase of 13% each year. If journal prices had indeed increased by 13% each year, what percentage increase would that give over 10 years? (Round your answer as a percentage to the nearest whole number.)

Answers

Answer:

300%

Step-by-step explanation:

Here we have an exponential function, and it is one of the most important functions in the mathematics. In this case, the independet variable is the exponent.

Here we have that represented price increase of 13% each year, which means that 1" alt="b=1.13>1" align="absmiddle" class="latex-formula">  in our exponential function, while represent the journal price at the begining.

So we get the following function:

where represents number of years. After 10 years, we get:

The conclusion is that over 10 years, the percentage of increase would be about 300%.

Choose the answer based on the most efficient method as presented in the lesson. Ir the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then what should the next step be?
subtract 5x
add 8
subtract 3

Answers

Answer:

We will subtract 3 from both sides.

Step-by-step explanation:

The first step in the solution of the equation is "subtract 2x,"

=>

Now the next step will be subtract 3 from both sides.

=>

And x = -11/3

The next step is to subtract three making it -11 You have already combined your coefficients so your equations is -11=3x

2.twelve times the sum of a number plus twenty four

3.twenty-four more than twelve times a number

4.twelve times the difference of a number and twenty four

Answers

Answer:

3

Step-by-step explanation:

when you see a variable with a number it means a number times a number. so for instance if you see 2x its 2 times a number x. then you see +12 which means addition therfore when you have a bag of apples and u add apples to the bag you have two more apples in your bag of apples if that nakes sense.

hope that helps!
