Consider the function f with domain (-2, : 3|22 – 1| if – 2 < x < 1 2x2 + 2x – 4 f(x) = 3 if x = 1 x!/(1-æ) if 1< x Is f continuous at x = 1? If not, what type of discontinuity does f have at x = 1?

all the options are: is or is not

1).answers these questions: a).Find the domain and the range of y = x^2-5 b). Evaluate piecewise function{x^2+2 x<=1. ,  2x^2+2 x>1 f(-2)? f(0)? f(1)?
