I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut thex-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set of data points from observati...

Answer to: Find the maximum value of the quadratic function. y = 7x^2 +28x -35 By signing up, you'll get thousands of step-by-step solutions to...
Step 2: Factor the derivativeNext, we can factor the derivative to find critical points. f′(x)=6(x2−x−6) Now, we factor the quadratic expression: x2−x−6=(x−3)(x+2) Thus, we have: f′(x)=6(x−3)(x+2) ...
An example of a quadratic function with only one root is the function x^2. This is only equal to zero when x is equal to zero. It might also happen that there are no roots. This is, for example, the case for the function x^2+3. Then, to find the root, we have to have an ...
Finding the minimum or maximum of a function is important in mathematics. Often you want some quantity to be maximal, such as profits or capacity. Minima is useful when looking at a cost function.
