WebMar 8, 2024 · Solution: To find intervals of increase and decrease, you need to differentiate the function concerning x. Therefore, f’ (x) = -3x 2 + 6x. Now, taking out 3 common from the equation, we get, -3x (x – 2). To find the values of x, equate this equation to zero, we get, f' (x) = 0 ⇒ -3x (x – 2) = 0 ⇒ x = 0, or x = 2. cherry delite

WebJul 18, 2024 · h(x) = − 2x2 + 4x − 9 Solution Any real number, negative, positive or zero can replace x in the given function. Therefore, the domain of the function h(x) = 2x2 + 4x − 9 is all real numbers, or as written in interval notation, is: D: ( − ∞, ∞). WebThe rate of change would be the coefficient of x. To find that, you would use the distributive property to simplify 1.5 (x-1). Once you do, the new equation is y = 3.75 + 1.5x -1.5. Subtract 1.5 from 3.75 next to get: y = 1.5x + 2.25. Since 1.5 is the coefficient of x, 1.5 would be the rate of change. Hope that helps!
