Creating formula for graph.

[kacdro]

Hello,

I'm currently doing my math exploration. I decided on topic, where I'm trying to formulate an equation for my curve/graph. However I have no idea how to do it. I spent few hours looking for solution, however I'm stuck in one point. Please guys help me. Below I give you my data. X-axis on top, and y on bottom.

15	20	25	30	35	40	45	50
295	301	308	316	334	359	389	432

What methods have they taught you? Are you doing regression equations in your graphing calculator, running the data points through an Excel spreadsheet, or some other method? How does this exercise relate to calculus (derivatives or integrals, etc)?

I'm stuck in one point. Please guys help me.

We can try to help, but you'll have to explain how far you've gotten and what is the "one point" where you're getting "stuck". Thank you!
