What is an exponential growth function?

Back

An exponential growth function is a mathematical expression of the form A = P(1 + r)^t, where A is the amount after time t, P is the initial amount, r is the growth rate, and t is time.

What is an exponential decay function?

Back

An exponential decay function is a mathematical expression of the form A = P(1 - r)^t, where A is the amount after time t, P is the initial amount, r is the decay rate, and t is time.

How do you add polynomials?

Back

To add polynomials, combine like terms by adding their coefficients while keeping the variable part the same.

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically written in the form f(x) = ax^2 + bx + c, where a, b, and c are constants.

Front

What does the graph of a quadratic function look like?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards depending on the sign of the coefficient a.

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on whether it opens upwards or downwards.

Front

How do you write an equation for exponential growth?

Back

An equation for exponential growth can be written as y = P(1 + r)^t, where P is the initial value, r is the growth rate, and t is time.

Front

What is the formula for solving for x in a linear equation?

Back

The formula for solving for x in a linear equation is x = (c - by)/a, where ax + by = c.

Front

What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables raised to whole number powers and their coefficients, combined using addition, subtraction, and multiplication.

Front

What are like terms in polynomials?

Back

Like terms are terms in a polynomial that have the same variable raised to the same power, allowing them to be combined.
