Question 1

Write interval notation for the following. Then graph the interval on a number line.

{x∣ x ≤ -0.5}

◦ (-∞, -0.5)

◦ (-0.5, ∞)

◦ [-0.5, ∞)

◦ (-∞, -0.5]

Question 2

Suppose that $2000 is invested at 5% interest, compounded monthly, for t years. The amount A in the account is a function of time. Find an equation for this function and state the domain of the function.
◦ A = 2000

^12t, Domain: {t|t ≥ 0}
◦ A = 2000

^12t, Domain: {t|t is a real number}
◦ A = 2000

^t, Domain: {t|t ≥ 0}
◦ A = 2000

^12t, Domain: {t|t ≥ 0}
