Write a function rule to represent the situation.
the total cost C for g grams of copper if each gram costs $5.84
Write a function rule using C and g as variables.
[ ] (Type an equation.)
C = 5.84g
Write a function rule that represents the situation.
The price p of a pizza is $6.95 plus $0.95 for each of the t toppings on the pizza.
p = [ ] (Use integers or decimals for any numbers in the expresssion. Do not include the $ symbol in your answer.)
p = 6.95 + 0.95t
Use a mapping diagram to determine whether the relation is a function.
[(2,6), (3,8), (3,5), (8,7), (4,10), (2,2)]
Which of the following mapping diagrams represents the relation?
The mapping diagrams given are as follows:
1)
2 -> 6
3 -> 8
3 -> 5
8 -> 7
4 -> 10
2 -> 2
2)
2 -> 6
3 -> 8
3 -> 5
8 -> 7
4 -> 10
2 -> -
3)
2 -> 6
3 -> 8
3 -> 5
8 -> -
4 -> 10
2 -> 2
4)
2 -> 6
3 -> 8
3 -> -
8 -> 7
4 -> 10
2 -> 2
Based on the given relation [(2,6), (3,8), (3,5), (8,7), (4,10), (2,2)], we can see that there are multiple outputs for the same input in the mapping diagram 1 and mapping diagram 3. Therefore, neither mapping diagram represents the given relation as a function.
The function rule to represent the situation would be:
C = 5.84g
In this equation, C represents the total cost in dollars and g represents the weight of copper in grams. By multiplying the cost per gram ($5.84) by the weight in grams (g), we can calculate the total cost of the copper.
