On a coordinate plane, a red curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A blue curved line with an upward arc, labeled f of x, crosses the y-axis at (0, 4) and the x-axis at (2, 0).

Question illustration
A
f(0) = 2 and g(–2) = 0
B
f(0) = 4 and g(–2) = 4
C
f(2) = 0 and g(–2) = 0
D
f(–2) = 0 and g(–2) = 0

Question illustration
A
[–1, 0]
B
[1, 2]
C

Question illustration
A
f(x) ≥ 0 over the interval [5, ∞).
B
f(x) ≤ 0 over the interval [–1, ∞).
C
f(x) > 0 over the interval (–∞, 1).
D
f(x) < 0 over the interval (–∞. –1).

Question illustration
A
(0, 6)
B
(1, 0) and (2, 0)
C
(1, 0), (2, 0), and (–3, 0)
D
