Front

What is a y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis. It is the value of y when x = 0.

Front

What is an x-intercept?

Back

The x-intercept is the point where a graph intersects the x-axis. It is the value of x when y = 0.

Front

Define zeros of a function.

Back

Zeros of a function are the values of x for which the function f(x) = 0.

Front

What does the range of a function represent?

Back

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

Front

How do you determine if a graph is increasing or decreasing?

Back

A graph is increasing on an interval if the y-values rise as x-values increase. It is decreasing if the y-values fall as x-values increase.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex is the highest or lowest point of a parabola, representing the maximum or minimum value of the function.

Front

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is f(x) = ax^2 + bx + c, where a, b, and c are constants.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the value of x into the function and simplify.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.

Front

What is the difference between a linear 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.
