when x is not 2 you can just plug in points but its a linear upwards line going through the origin and the point (4,2) but when x =2 you just put a point at (2,2) Piecewise functions

1. Identify common domain. Look for overlapping xvalues of the piecewise functions. If the given functions do not have any common domain, you cannot multiply them. For example, if

To solve piecewise functions 1st you evaluate the problem then solve for the

x^21 is negative on the range of integration, so only the "x+1" piece of f is relevant. Plugging x^21 into f gives f(x^21) = (x^21) + 1 = x^2. So, the integral is just
