Hey guys

I'm so close to finishing this course I can taste it!

I've been stuck on this question forever because I just don't even know what I'm supposed to do. I have a feeling I'm overthinking it...

We're given a table of values and asked to "use graphing technology to determine an equation that fits:

a. the linear model

b. the quadratic model

c. the exponential model"

Like I said, I'm not sure how exactly to go about this...

for a. I used the first and last point given in the table of values to get the slope and subbed those points and the slope into y=mx+b to get the value of b.

I have a feeling that's wrong though... And I'm not sure how I'm supposed to do it.

I'm pretty much completely lost for b and c.

Any input would be really appreciated. Thanks a lot, guys!
