Answer:

If the graph of a function f is known, it is easy to determine if the function is 1 -to- 1 . ... If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .

The answer I believe is 5 because 2 vases hold 10 red roses and 5 yellow roses. But since the person has 3 vases but it has to be the same amount as the first person. They would both have 30 flowers in their vases. But then each of the vases has 6 red roses so you just do 30 divided by 6 and you get 5.

Evaluate piecewise functions
Vika [28.1K]

Answer:

F(4) = 9

Step-by-step explanation:

Notice that for f(4), we need to use the function definition for the partitioned Domain that includes x = 4, and that is the expression :

f(x) = x^2-7

Therefore:

f(4) = 4^2-7 = 16-7 =9

Given :

Emily reads 24 friction books and 2 nonfiction books.

Number of fiction books she read =24

Number of nofiction boos she read = 2

Total number of books = 26

To Find :

What is the ratio of the number of fiction books she read to the total number of books that she read ?

Solution :

Total number of books that she read=24+2=26

number of fiction books she read=24

Thus ratio of number of fiction books to total number of books that she read

 ⇒  \frac{24}{26}

 ⇒  \frac{12}{13}

 ⇒ 12: 13

Hence  ratio of number of fiction books to total number of books that she read 12 : 13
