WebA function that is completely increasing or completely decreasing on the given interval is called monotonic on the given interval. Usually, by looking at the graph of the function one can say whether the function is increasing or decreasing or neither. WebIn determining intervals where a function is increasing or decreasing, you first find domain values where all critical points will occur; then, test all intervals in the domain of the …

WebSolution Analyze each function. The function can be represented as f (x) = 60x f ( x) = 60 x where x x is the number of days. The slope, 60, is positive so the function is increasing. This makes sense because the total number of texts increases with each day. WebThe slope determines if the function is an increasing linear function, a decreasing linear function, or a constant function. f(x) = mx + b is an increasing function if m > 0. f(x) = mx + b is a decreasing function if m < 0. f(x) = mx + b is a constant function if m = 0.
