Front

What is an x-intercept in a graph?

Back

An x-intercept is a point where the graph intersects the x-axis, meaning the value of y is zero at that point.

Front

How do you determine the range of a function from its graph?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce, which can be identified by looking at the vertical extent of the graph.

Front

What is a relative minimum in a graph?

Back

A relative minimum is a point on the graph where the function value is lower than the values of the function at nearby points.

Front

What is a relative maximum in a graph?

Back

A relative maximum is a point on the graph where the function value is higher than the values of the function at nearby points.

Front

What does it mean for a function to be even?

Back

A function is even if its graph is symmetric with respect to the y-axis, meaning that f(x) = f(-x) for all x in the domain.

Front

What does it mean for a function to be odd?

Back

A function is odd if its graph is symmetric with respect to the origin, meaning that f(-x) = -f(x) for all x in the domain.

Front

What is the significance of the range being (-∞, ∞)?

Back

If the range of a function is (-∞, ∞), it means that the function can take any real number as an output.

Front

How can you identify the symmetry of a function from its graph?

Back

You can identify symmetry by checking if the graph is unchanged when reflected over the y-axis (even), the origin (odd), or if it has no symmetry.

Front

What is the difference between a function's domain and range?

Back

The domain is the set of all possible input values (x-values) for the function, while the range is the set of all possible output values (y-values).

Front

How do you find the number of x-intercepts in a graph?

Back

The number of x-intercepts can be found by identifying the points where the graph crosses the x-axis.
