# Assignment 7

In this assignment you will write a function called
`riemannLeftSum` that takes four arguments:
`f, a, b, ` and `n`.
`f` will be a function input; `a` is
the left limit of integration; `b` is the right
limit of integration; and `n` is the number of
subintervals for a left Riemann sum approximation to
the integral. The function will do two things:
it will create a plot as in Figure 1; and it will return
the value of the Riemann sum.

`fill()`function with a 'FaceAlpha' value of 0.5.

The assignment is worth 40 points and is due at 9 AM on Friday, 20 October. The assignment is turned in when the .m file appears as an attachment to a message in the instructors email inbox.
