Question 1
Find the points of intersection of the curves
y =

and y =

.
◦ (-2,

) and (2,

) and (0, 0)
◦ (2,

) and (-2,

) and (0, 0)
◦ (2,

) and (-2,

)
◦ (2,

) and (-2,

)
◦ These curves do not intersect.
Question 2
What are the domain and range of f(x) = x
3 - x + 13?
◦ domain and range are both (-∞, ∞)
◦ domain (-∞, ∞), range [0, ∞)
◦ domain (-∞, ∞), range [13, ∞)
◦ domain (-∞, ∞), range (-∞, 13]
◦ domain (-∞, ∞), range [12, ∞)
