Domain of Combined Functions

State the domain:

• (-oo, oo)

• (-oo, 6) U (-2, oo)

• (-oo, -2) U (-2, 6) U (6, oo)

• (-oo, -2) U (-2, 0) U (0, 6) U (6, oo)

State the domain:

• (-oo, 1) U (1, oo)

• (-oo, -1) U (-1, 1) U (1, oo)

• (-oo, oo)

• (-oo, -1] U [-1, 1] U [1, oo)

State the domain:

• (-oo, oo)

• (-oo, -2) U (-2, 2) U (2, oo)

• (-2, 2)

• (-oo, -2) U (2, oo)

State the domain:

• (-oo, oo)

• [3, oo)

• (3, oo)

• (-oo, 3) U (3, oo)

What is the domain of (f+g)(x) if f(x) = 1/(x - 2) and g\left(x\right)=\sqrt{x^2-9}

• {x | x >= 3}

• {x | x > 3}

• {x | x >= 3 or x <= -3, x not equal to 2}

• {x | x >= 3, x not equal to 2}

• {x | x >= 3 or x >= -3, x not equal to 2}
