What? Where did h, a, and q come from? Thats a general form for a quadratic but you need to use the information from this problem.davie08 said:okay would you use R=a(q-h)^2 + k
If you sell 10 items for $5 each, how much money will you receive?davie08 said:I really have no clue what to use to figure this out can someone just explain what I have to use and then I will understand it and practice it until I'm ready to use it on a test.

A quadratic function is a polynomial function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants and x is the variable. It is a type of function that has a degree of 2, meaning the highest exponent in the equation is 2.
To solve a quadratic function, you can use methods such as factoring, completing the square, or the quadratic formula. These methods involve manipulating the equation to isolate the variable, x, and determine its value. You can also use a graphing calculator to find the x-intercepts or roots of the function.
Solving a quadratic function means finding the value(s) of x that make the function equal to a given y-value. Graphing a quadratic function means plotting points to show the relationship between x and y values, and the shape of the graph can tell you if the function has real or imaginary roots.
Quadratic functions can be used to model real-life situations, such as projectile motion, population growth, and profit maximization. They can help predict outcomes and make informed decisions in fields such as engineering, physics, and business.
Some common mistakes to avoid when solving quadratic functions include forgetting to distribute negative signs, making calculation errors, and forgetting to check for extraneous solutions. It is also important to be familiar with the properties of quadratic functions and how they can be manipulated to solve for x.
