What is a relative maximum in a polynomial function?

Back

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

Front

What is a relative minimum in a polynomial function?

Back

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

Front

How do you find relative maximums and minimums in a polynomial?

Back

Relative maximums and minimums can be found at turning points, which are points where the derivative of the function changes sign.

Front

What is a turning point in the context of polynomial functions?

Back

A turning point is a point on the graph where the function changes from increasing to decreasing or from decreasing to increasing.

Front

What is the significance of the first derivative in finding relative extrema?

Back

The first derivative indicates the slope of the function; where it equals zero, the function may have a relative maximum or minimum.

Front

What is the second derivative test?

Back

The second derivative test helps determine the concavity of the function at a critical point: if the second derivative is positive, it's a relative minimum; if negative, it's a relative maximum.

Front

What does it mean if a polynomial has no relative maximum or minimum?

Back

If a polynomial has no relative maximum or minimum, it means the function is either always increasing or always decreasing.

Front

What is the difference between relative and absolute extrema?

Back

Relative extrema are the highest or lowest points in a specific interval, while absolute extrema are the highest or lowest points over the entire domain of the function.

Front

How can you identify relative extrema from a graph?

Back

Relative extrema can be identified on a graph as the peaks (maximums) and valleys (minimums) of the curve.

Front

What is the role of critical points in finding relative extrema?

Back

Critical points are where the first derivative is zero or undefined; they are potential locations for relative maximums and minimums.
