End of week of Dec 16-20/2024 Practice Review Activity

Front

What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

How can you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

Front

What is the value of any non-zero number raised to the power of zero?

Back

Any non-zero number raised to the power of zero is equal to 1.

Front

What are x-intercepts?

Back

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

Front

How do you find the x-intercepts of a function?

Back

To find the x-intercepts, set the function equal to zero and solve for x.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, used to predict values.

Front

How do you interpret the slope of a line of best fit?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable.

Front

What does it mean to simplify an expression?

Back

Simplifying an expression means to reduce it to its simplest form, combining like terms and eliminating unnecessary parts.

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, representing the output when the input (x) is zero.

Front

What is the difference between a linear function and a non-linear function?

Back

A linear function has a constant rate of change and graphs as a straight line, while a non-linear function does not have a constant rate of change and can curve.
