What is the formula for exponential decay?

Back

y = a(1 - r)^t, where 'a' is the initial amount, 'r' is the decay rate, and 't' is time.

Front

How do you find the vertex of a quadratic function represented by the equation y = ax^2 + bx + c?

Back

The vertex can be found using the formula x = -b/(2a).

Front

What does the slope of a linear equation represent?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

How do you determine if a set of ordered pairs represents a function?

Back

A set of ordered pairs represents a function if no two pairs have the same first element.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the value of y when x = 0.

Front

What is the significance of the coefficient of x in a linear equation?

Back

The coefficient of x represents the slope of the line.

Front

How do you evaluate a function at a given point?

Back

Substitute the given point into the function's equation.

Front

What is the general form of a quadratic equation?

Back

The general form is y = ax^2 + bx + c, where a, b, and c are constants.

Front

What does the term 'exponential growth' mean?

Back

Exponential growth occurs when a quantity increases by a constant percentage over time.
