How do you write an exponential function whose graph passes through (0,-0.3) and (5,-9.6)?
Please see the explanation for steps leading to a solution.
An exponential function is:
We can find the value of C, using the point
We can use the point
Divide both side by
Take the natural logarithm of both sides, to make the exponential disappear:
Divide both sides by 5:
The above is the same as
The exponential function is:
