For each function, do the following: a) state the name of the function, b) identify the independent and dependent variable, c) i

Lostsunrise [7]

Answer:

Given the function in the question

f(x) = |x-3| + 2

a) state the name of the function

Absolute value function

since it is similar to f(x) = |x|

b) identify the independent and dependent variable

x = independent variable (input variable)

f(x) or y = dependent variable (output variable)

The variable which we assign the value we call the independent variable, and the other variable is the dependent variable, since it value depends on the independent variable.

c) identify the rule

A function is an equation that has only one answer for y for every x.

d) evaluate the function

given x = -5

f(-5) = |-5 - 3| + 2

= |-8| + 2

= 8 +2

= 10

AlekseyPX

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 27 are: 1, 3, 9, 27

Then the greatest common factor is 9.

The greatest number of flowers that could be in a bouquet is 9 flowers
