math homework help part2!!?

Question

okay the thing im doing in my math book is called numbers to functions its 9th grade math and wat we did in class was we(my teacher put it this way) have a machine and we put in 2 and 4 comes out and i dont get any of i do better with exponets and i hate them with a passion so numbers and functions are lower than dirt right im sorry but that is the best way i can explain it cuz the way its suppose to be drawn out is in a t chart form i gess and one side says in and the other side says out so u put 2 in on the in side and 4 comes out on the out side and so on and so forth and then it goes into words like house goes in and the nmber 4 comes out

Answer 1

Think of a math operation: What do you do to the first number to get the 2nd number?
2 +/-/x// 1,2,3,4,5,6,7,8,9,... = 4
There are several possibilities -
2 +2 = 4, 2 x2 =4

Usually, functions provide more than 1 example, such as:
2 =4
6 =12
10 = 20
If this were the case, the function is x2.

Answer 2

Are you in california? I swear the ****** math books they use here confuse people more than teach them. We had that stupid function machine when I was in high school. I understand math well, I got an A in calculus, but I still don't understand the function machine. I know how to graph a function, but the stupid machine analogy just sucks.

Answer 3

uh, what exactly are you asking?

The only ways that 2 could come out as a 4 is if it's multiplied by 2 (itself) or if 2 is added to it.

Answer 4

fifty 3.seventy 5=x+y x is the quantity paid for money in X account and y is money paid for money in Y account. X situations .0.5 = x Y situations .04 = y two hundred+ X = Y wait... do you have two hundred greater in the account which will pay 5.5% than the 4% account or any incorrect way around?
