Using a Graph to Determine Where a Function is Increasing, Decreasing, or Constant. As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval.Algebra. Find Where Increasing/Decreasing f (x)=x^2+4x-5. f (x) = x2 + 4x − 5 f ( x) = x 2 + 4 x - 5. Graph the polynomial in order to determine the intervals over which it is increasing or decreasing.
