AP Precalculus Unit 1 Review

Front

What is the factored form of a polynomial with roots x=-2, x=5, x=2/3?

Back

y=(x+2)(x-5)(3x-2)

Front

What does the phrase 'over equal-length interval' mean?

Back

The x-values are evenly spaced.

Front

True or False: Between 2 real zeros of a polynomial, there must be at least one local minimum or local maximum.

Back

TRUE

Front

What is an even function?

Back

An even function is symmetric over the y-axis and satisfies f(-x) = f(x).

Front

What is an odd function?

Back

An odd function is symmetric about the origin and satisfies g(-x) = -g(x).

Front

If the graph of a function crosses the x-axis, what does that indicate about the multiplicity of that zero?

Back

It indicates that the multiplicity is odd.

Front

What is the definition of a polynomial?

Back

A polynomial is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial.

Front

What is a local maximum?

Back

A local maximum is a point where the function value is higher than all nearby points.

Front

What is a local minimum?

Back

A local minimum is a point where the function value is lower than all nearby points.
