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
Answer: the mean is 44
Explanation: add up all the numbers and then divide by how many numbers there are
Answer: 250 cameras; $10,000 spent; 15,000 made
Step-by-step explanation:
1) FInd the profit. 60-40=20. This means that they make a profit of $20 per camera.
2) How many cameras to break even? 5000/20=250. The answer is 250 cameras!
3) How much money has been spent? 40x250= $10000 spent.
4) How much money has been made? 60x250= $15000 made.
