What does a horizontal shift in a function mean?

Back

A horizontal shift occurs when the graph of a function moves left or right on the coordinate plane. For example, in the function g(x) = (x - 7.5)², the graph shifts 7.5 units to the right.

How do you express exponential growth in a function?

Back

Exponential growth can be expressed as n = a(b)^h, where 'a' is the initial amount, 'b' is the growth factor, and 'h' is the time.

Back

A function is increasing if, as the input (x) increases, the output (f(x)) also increases.

Front

What is the vertex of a parabola?

Back

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

What is the difference between a linear function and a quadratic function?

Back

A linear function has a constant rate of change and is represented by a straight line, while a quadratic function has a variable rate of change and is represented by a parabola.
