Unit 4 Vocab - Rational Functions

We stand and fight!

• We run and hide!

• We negotiate and compromise!

• We surrender!

• We will!

Rational Functions have both a numerator a denominator

• False.
• True
• Rational Functions have only a numerator.
• Rational Functions have only a denominator.

A Rational Function is a ratio function of polynomial can't divide into 0.

• The denominator polynomial must be equal to zero.
• The numerator polynomial cannot be equal to zero.
• The denominator polynomial cannot be equal to zero.
• A Rational Function is a ratio function of polynomial can divide into 0.

When transforming Rational Functions, we get y = a/x-h +k. What does a, h, and k do?

• a represents the horizontal stretch or compression, h represents the vertical shift, and k represents the horizontal shift.
• a represents the vertical stretch or compression, h represents the vertical shift, and k represents the horizontal shift.
• a represents the horizontal stretch or compression, h represents the vertical shift, and k represents the vertical shift.
• a represents the vertical stretch or compression, h represents the horizontal shift, and k represents the vertical shift.

What is a parent function of a Rational Function

• f(x) = 1/x^2
• f(x) = 1/x
• f(x) = x
• f(x) = x^2

There are two asymptotic lines on a Rational Function. Vertical and Horizontal.

• Ascending and Descending
• Vertical and Horizontal
• Curved and Straight
• Parallel and Perpendicular

As the horizontal change occurs, vertical asymptotic change. If vertical change occurs, the horizontal asymptotic changes occur.

• False
• Sometimes.
• True.
• It depends.

A Rational Function will never reach an asymptote

• Depends on the function
• True
• Sometimes
• False

What are characteristics of Rational Functions in a graph.

• Vertical asymptotes, horizontal asymptotes, holes or points of discontinuity, x-intercepts, y-intercepts
• Reflection across the origin

When looking at the parent function function of a Rational Function, the domain is all real number except x=0

• All real numbers except x=1.
• All real numbers except x=2.
• All real numbers except x=0
• All real numbers except x=3.
