Answer: D
Step-by-step explanation:
David - f(x) Ronald - g(x)
f(x) = [tex]\sqrt[3]{x-1}[/tex]
f(2) = [tex]\sqrt[3]{2-1}[/tex] = 1.00 1.26
f(4) = [tex]\sqrt[3]{4-1}[/tex] = 1.44 1.59
f(6) = [tex]\sqrt[3]{6-1}[/tex] = 1.71 1.82
f(10) = [tex]\sqrt[3]{10-1}[/tex] = 2.08 2.15
The side length for Ronald's box is greater than David's.

Answer: (0, 4)
Step-by-step explanation:
f(x) is an absolute value graph with a vertex at (0, 3).
- f(x) is increasing from 0 to infinity ⇒ (0, ∞)
g(x) is a parabola reflected across the x-axis with a vertex at (4, 12).
- g(x) is increasing from negative infinity to 4 ⇒ (-∞, 4)
Together: f(x) and g(x) are both increasing from 0 to 4 ⇒ (0, 4)
