Q: What is a piecewise function?

A:

Q: Determine the domain of the function. G(u) = 1/ (u2 -4)

A: Consider the given function. Gu=1u2-4 To find the domain, put the denominator equal to zero.…

Q: Refer to the functions f and g and evaluate the functions at x =-2. f = {(2, -1), (1, 1), (-4, -6),…

A: (f+g)(-2)=f(-2)+g(-2)  Substitute   f(-2)=-8  ,    g(-2)=-5in the above equation
