Practice Problems on Monotonicity and Concavity. I. Determine the intervals over which f increases/decreases. a. f(x) = x. 4- 3x. 3. Answer: f increases on (9/4, ∞) and decreases on (-∞, 9/4). f is concave downwards on (0, 3/2). f is concave upwards on (-∞, 0) and on (3/2, ∞). b.You can also determine the concavity of a graph by imagining its tangent lines. If all the tangent lines are below the graph, then it's concave up. If all the tangent lines are above the graph, then it's concave down. If the tangent line is on the actual graph, then you have an inflection point (i.e. a straight line). The picture below ...Here’s the best way to solve it.
