Answer:


  • f(x)=√(x+3)

  • f(x)=(1)/((x-2)(x-4))

Explanation:

a) It can be convenient to use the square root function as one being defined only for values greater than or equal to some number. Here, we need to shift that function 3 units to the left, so its domain is [-3, ∞).


f(x)=√(x+3)

__

b) One way to put holes in a function is to put vertical asymptotes there. This function can be defined to have vertical asymptotes at x=2 and x=4 so those values are excluded from the domain.


f(x)=(1)/((x-2)(x-4))
