What is the quotient rule in calculus?

Back

The quotient rule states that if you have a function that is the quotient of two functions, f(x) = g(x)/h(x), then the derivative is f'(x) = (g'(x)h(x) - g(x)h'(x))/[h(x)]^2.

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and a ≠ 0.

Front

How do you find the x-intercepts of a quadratic function?

Back

To find the x-intercepts of a quadratic function, set y = 0 and solve the equation ax^2 + bx + c = 0 using factoring, completing the square, or the quadratic formula.
