Question

When comparing the f(x) = –x2 + 2x and g(x) = log(2x + 1), on which interval are both functions positive?

(–∞, 0)
(0, 2)
(2, ∞)
(∞, ∞)

Answer 1

Considering their graphs, the interval in which both functions are positive is:

(0, 2)

When are the functions positive?

A function is positive when it's graph is positioned above the x-axis.

Looking at the graph, the functions are positive for x between 0 and 2, hence the interval in which both functions are positive is stated as follows:

(0, 2)
