Given function f(x) = -5x + 8.

To find f(x-1), we substitute (x-1) in place of x in the function f(x).

Therefore, f(x-1) = -5(x-1) + 8.

Simplify the expression:

f(x-1) = -5x + 5 + 8.

Combine like terms:

f(x-1) = -5x + 13.

Therefore, \boxed{f(x-1) = -5x + 13}.

The average undergraduate cost per tuition, fees, room, and board for all institutions last year was $26,025. A random sample of 40 institutions of higher learning this year indicated that the mean tuition, fees, room, and board for the sample was $27,690, and the population standard deviation is $5492. At the 0.05 level of significance, is there sufficient evidence that the cost has increased? (Remember to follow the steps in hypothesis testing)
