f(x)= 0.469x^2 + 0.758x + 0.44 (0

where f(x) is measured in billions of dollars and x=0 corresponds to 1999.

find the interval where f is increasing and decreasing

Chosen Answer:

f(x)= 0.469x^2 + 0.758x + 0.44 (0 This function is continuously increasing on (0,6)
Graph the function

or
f'(x) = 2(0.469) x +0.758
f'(x) = 0.938x+0.758
Substitute any value between 0 and 6
f'(x) > 0, so f must be increasing on (0,6)
