Exponential functions are in the form
ab^(x). In this equation,
b can be determined by figuring out the "common ratio" or the multiplier: the number that you have to multiply each
y value to get the next
y value. So, what do you have to mulriply
5 by to get
10. Or
10 by to get
20. Your answer to that question is your
b.

To get your
a, you simply need to find the
y value that corresponds to an
x value of
0. So, from the chart, what
y value corresponds to
x=0?

Now, just substitute the
a and
b you found into
ab^(x) and you've got your exponential function.

first find slope
5-10/-1-0= 5

find y-intercept
10=5(0)+B
b=-10

equation: y=5x-10
