Need help: Find the x-values, if any, at which f is not continuous. Which of the discontinuites are removable? f(x) = cos pi x/2/ and f (x) = -2x, xsquared-4x+1, x less than or = 2, x greater than 2?

Hi Leanne -- at the bottom left corner there is an "equation" button. Please type your question using that to avoid ambiguous notation.

i just re wrote the equations out again.
the original question still stands.
