Python List Comp and Lambda function

In calculus, we often want to look at the values of a function f(x) over an interval [a, bl. To get exactly n evenly-spaced points in the interval [a, b], we use the points of the form a, a + b - a, a + 2 b - a, a + 3 b - a, ..., a + (n - 1) b - a, b Plugging those into f(x) give us a list of values of the function: f(a), f (a + b - a), f(a + 2 b -a), f (a + 3 (b - a), ..., f(a + (n - 1)b - a), f(b) Write down, in one line if possible, a function named f_vals which takes as input a, b, n, and f, and returns the above list of function values (use a list comprehension to shorten your code)
