Answer:
A) {(1, 2), (1, 3), (1, 1)}
Step-by-step explanation:
The x variable repeats in (1,2), (1,3), (1,1) not making it a function.
Answer:
4,415.1515...
Step-by-step explanation:
To find the value of the number that 1457 is 33% of, we can change the percentage into a decimal then divide.
33% = 0.33
1457 / 0.33 = 4,415.1515...
Best of Luck!
Answer:
Positive
Step-by-step explanation:
When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.
Only the function in C has the range of all real numbers.
Later on, when you will be familiar with more type of functions you will know that when x is on the power range is usually only positive values or negative values if only not shifted, even if shifted it will only add to its range this numbers by which unit it was shifted.
B is shifted parabola. It has the range of {y| -3≤∞}
a)
he charges a fixed cost of $12, meaning a one-time charge of 12 bucks, plus 1.50 for each window.
1 window................ 12 + 1.5(1)
2 windows............. 12 + 1.5(2)
3 windows............. 12 + 1.5(3)
4 windows............. 12 + 1.5(4)
x windows............. 12 + 1.5(x)

b)
