• Review of algebraic concepts

• Overview of polynomial functions

What happens to the output of a polynomial function as the input values increase without bound?

• Output remains constant

• Output increases without bound

• Output fluctuates

• Output decreases without bound

What is the significance of the leading coefficient in determining the end behavior of polynomial functions?

• Indicates the maximum value of the function

• None of the above

• Determines the curvature of the graph

• Affects the direction the function approaches as input values increase

Which term dominates in a polynomial function as the input values increase?

• The term with the highest degree

• The constant term

• The term with the lowest degree

• All terms equally contribute

What does the term 'dominate' refer to in the context of polynomial functions?

• The term with the lowest coefficient

• The constant term in the polynomial

• The term that contributes least to the function's value

• The term with the highest exponent

What does a vertical asymptote in a graph indicate?

• An undefined function

• A hole in the graph

• A zero in the denominator without a corresponding zero in the numerator
