What is the x-intercept of a graph?

Back

The x-intercept is the point where the graph crosses the x-axis, meaning the value of y is zero.

Front

How many x-intercepts can a quadratic function have?

Back

A quadratic function can have zero, one, or two x-intercepts.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the linear parent function?

Back

The linear parent function is f(x) = x.

Front

What does it mean when we say 'y is a function of x'?

Back

It means that for every value of x, there is exactly one corresponding value of y.

Front

What are the roots of a function?

Back

The roots are the x-values where the function equals zero, also known as x-intercepts.

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, meaning the value of x is zero.

Front

What is the formula for calculating slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.
