How do you calculate the annual profit if a baker sells 400 pies using the profit formula?

Back

p(400) = 52(400) − 0.05(400)² = $12,800.

What is the standard form of a quadratic function?

Back

A quadratic function is in the form f(x) = ax² + bx + c, where a, b, and c are constants.

Front

What does it mean for a function to be equivalent?

Back

Two functions are equivalent if they produce the same output for every input.

Front

What is the factored form of the quadratic function q(x) = 9x² − 24x + 16?

Back

q(x) = (3x − 4)².

Front

How do you combine like terms in an expression?

Back

Combine terms that have the same variable raised to the same power.
