What is the difference of squares formula?

Back

The difference of squares formula states that for any two numbers a and b, the expression a² - b² can be factored as (a - b)(a + b).

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

Back

To find the x-intercepts of a quadratic function in the form y = ax² + bx + c, set y = 0 and solve the equation ax² + bx + c = 0 using factoring, completing the square, or the quadratic formula.

What is the minimum value of a quadratic function?

Back

The minimum value of a quadratic function in the form y = ax² + bx + c (where a > 0) occurs at the vertex, which can be found using the formula x = -b/(2a). Substitute this x-value back into the function to find the minimum y-value.

What is the formula for rate of flow?

Back

The formula for the rate of flow is R = V/t, where R is the rate, V is the volume, and t is the time.

Front

What are the units for measuring rate in the formula R = V/t?

Back

The appropriate unit for the rate R in the formula R = V/t, where V is in gallons and t is in seconds, is g/s (gallons per second).

What does it mean for a function to be increasing or decreasing?

Back

A function is increasing on an interval if the output values rise as the input values increase. It is decreasing if the output values fall as the input values increase.
