What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c, where a ≠ 0

Front

Define a polynomial function.

Back

A function that can be expressed in the form f(x) = a_nx^n + a_{n-1}x^{n-1} + ... + a_1x + a_0, where a_n, a_{n-1}, ..., a_0 are constants.

Back

y = a(x - h)^2 + k, where (h, k) is the vertex.

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points x_1 and x_2 in that interval, if x_1 < x_2 then f(x_1) < f(x_2).

Front

What is the quadratic formula?
