When a < 0, the quadratic expression f(x) = ax2 + bx + c has a maximum value at x = -b/2a.The domain of any quadratic function is the set of all real numbers.Methods to Solve Quadratic EquationsA quadratic equa
A ball is thrown upward from the top of a 40 foot high building at a speed of 80 feet per second. The ball’s height above ground can be modeled by the equationH(t)=−16t2+80t+40.H(t)=−16t2+80t+40. a. When does the ball reach the maximum h...

Write a quadratic equation for revenue. Find the vertex of the quadratic equation. Determine the yy-value of the vertex.Example: Finding Maximum Revenue The unit price of an item affects its supply and demand. That is, if the unit price goes up, the demand for the item will usually decrea...
This formula is known as the quadratic formula. We have used a simple way toprove quadratic formulawe can put values of a, b and c from any equation and find the value of x (the variable) by directly using this formula. IB Mathematics tutors can also explain the concept of conjugate ro...
If we graph this equation, we can see three important things: The x-intercepts tell us how many cupcakes we need to sell just to break even (where profit is zero). The top of the curve (the vertex) shows us the number of cupcakes that gives the maximum profit. The shape of the gra...
Find the vertex, the line of symmetry, and the maximum or minimum value of f(x). Graph the function. Consider the quadratic equation f(x)=x^2-9x+18 (a) find the vertex (b) find the axis of symmetry and (c) determine whether there is a ...
So what is the value of x? Obviously, if x is positive (i.e., x>0), then 1/x is positive, which means x>1 so as to satisfy the above equation. Multiplying both sides by x, we have x2=1+x, which means that x must be less than 2. Otherwise, the left-hand side x2 is ...
