Determine whether f(x) is continuous everywhere throughout its domain.

Question

Is f(x)= -100x + 600 if 0 ≤ x < 5
            -100x + 1100 if 5 ≤ x < 10
            -100x +1600 if 10 ≤ x < 15

Determine whether f(x) is continuous everywhere throughout its domain.

Answer 1

The functions are all polynomials.  They are continuous everywhere.  Is this really the question?
