What is an exponential function?

Back

An exponential function is a mathematical function of the form f(x) = a * b^x, where a is a constant, b is a positive real number, and x is the exponent.

What is the parent function of a quadratic function?

Back

The parent function of a quadratic function is f(x) = x^2.

Front

How do you find the vertex of a quadratic function in standard form?

Back

For a quadratic function in the form y = ax^2 + bx + c, the vertex can be found using the formula x = -b/(2a).

Front

What is the vertex of the function y = x^2 + 3x + 5?

Back

The vertex is (-1.5, 2.75).

Front

What is the general form of a linear function?

Back

The general form of a linear function is f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, represented as (0, f(0)).

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value).

Front

What is the significance of the x-intercepts of a function?

Back

The x-intercepts are the points where the graph of the function crosses the x-axis, indicating the values of x for which f(x) = 0.

Front

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form ax^2 + bx + c = 0.
