Free Functions Concavity Calculator - find function concavity intervlas step-by-step. How to Calculate Percentage Increase. Subtract final value minus starting value. Divide that amount by the absolute value of the starting value. Multiply by 100 to get percent increase. If the percentage is negative, it means there was a decrease and not an increase.Correct answer: (−5, 1) Explanation: To find when a function is decreasing, you must first take the derivative, then set it equal to 0, and then find between which zero values the function is negative. First, take the derivative: y′ = x2 + 4x − 5. Set equal to 0 and solve: x2 + 4x − 5 = 0.
