What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where a is a constant, b is a positive real number, and x is the exponent. It models growth or decay processes.

What does the inequality y ≥ 250,000 represent in a population model?

Back

It indicates that the population is at least 250,000, meaning the population cannot fall below this value.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What does the inequality -9 < x ≤ 2 signify?

Back

It means that x can take any value greater than -9 and up to and including 2.

Front

What is the formula for exponential growth?

Back

The formula for exponential growth is n = n_0 * b^t, where n_0 is the initial quantity, b is the growth factor, and t is time.

Front

What does it mean for a function to double?

Back

A function doubles when its output value becomes twice its previous value, often modeled by an exponential function.

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 is the significance of the coefficients in a quadratic function?

Back

The coefficients determine the shape and position of the parabola represented by the quadratic function.

Front

What does the term 'projectile motion' refer to?

Back

Projectile motion refers to the motion of an object that is thrown or projected into the air, subject to the force of gravity.
