Answer:
Step-by-step explanation:
Its not a function. The reason its not a function is because it doesnt pass the vertical line test. You could graph these points physically or you could think about it. The domain is the x value, while the range is the allowed y values. So by having the same x value relate to two different y values, just makes no sense. Imagine the function is x+4 and we are given in that graph that when x equals 6, the y equals 9 and 10. That isnt possible because we know the answer is 10, not 9, it cant be both.
Another way you could prove this is by graphing. If you try to take the slope in that interval where 6 coorelates to two y values. The change in y is 1, but the change in x is 0. When you divide 1/0, your calculator blows up. Try it
its a sqaure so the angles are 90 degress each.
90 - 38 = 52
answer: C. 52
Calculate for 3 days: 2,400 x 3 = 7,200
Calculate 1 day per hour: 2,400 ÷ 24 = 100
Calculate for 6 hours: 100 x 6 = 600
7,200 + 600 = 7,800 watt-hours
Answer: -5 and 2
Because it equals 3 when added.
And -10 when multiplied.
