Question 151552: What is the y-intercept of the graph of y = 2^x + ^2?
I am a little confused but I think
the ^x and ^2 are both exponents,
so x = 0
2(2) = 4
answer 0, 4
Am I correct?
Thanks in advance for your help!

Demand equation. Helen's Health Food usually sells 400 can of ProPac Muscle Punch per week when the price is $55 per can. After experimenting with prices for some time. Helen has determined that the weekly demand can be found by using the equation
d=600-40p
where d is hte number ofcans and p isthe price per can.
a) WillHelen sell more or less Muscle Punch if she raises her price from $5 ?
b)What happens to her sales every time she raises her price by $1 ?
c) Graph the equation.
d) What is the maximum price hat she can charge and still sell at least one can?

Set A
x = 6,6,6 and y = 1,2,3
Set B
x = 5,5,1/3 and y = -1,2,5
Set C
x = 1,2,3 and y = 3,4,5

Question 152574: We were given a set of data points today in class. We were told to find an equation for these data points. The equation pertains to graphing so I put the question in this category. I'm studying Patters & Relationships in Algebra 2 currently. Data is the X and Y coordinates.
X........Y
610.....915
631.....946
652.....978
673.....1009
Here's what I know from looking at this:
1) The X is independent variable, Y is dependent variable.
2) It is NOT linear because there is not linear progression in the Y
The equation I think might be correct is Y=.0165*X^3
Yet I contractdict it when I plug in the actual X coordinates for example..
Y=.0165*610^3
Y=.0165*226981000
Y=3745186.5 when it should be 915? What is up with that?
Please provide me with the correct equation and tell me how you found it. Thanks!
