What is Exponential Decay?

Back

Exponential Decay describes a process where a quantity decreases at a rate proportional to its current value, often represented by the function f(x) = a(1 - r)^x, where 0 < r < 1.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

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 are roots or x-intercepts?

Back

Roots or x-intercepts are the points where a function crosses the x-axis, meaning the output value (y) is zero.

Front

What is Linear Growth?

Back

Linear Growth occurs when a quantity increases by a constant amount over equal intervals, represented by a linear function f(x) = mx + b, where m > 0.

What is Linear Decay?

Back

Linear Decay occurs when a quantity decreases by a constant amount over equal intervals, represented by a linear function f(x) = mx + b, where m < 0.

What is Exponential Growth?

Back

Exponential Growth describes a process where a quantity increases at a rate proportional to its current value, often represented by the function f(x) = ae^(rx), where r > 0.

Front

How do you find the slope of a line given two points?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is a vertex in a parabola?

Back

The vertex is the highest or lowest point of a parabola, depending on its orientation.
