Unit 4 Review - Rational Functions PART 1

Front

Back

The constant of variation is denoted by k.

What is the equation of a rational function?

Front

How do you find the horizontal asymptote of a rational function?

Back

The horizontal asymptote can be found by analyzing the degrees of the numerator and denominator.

Front

Given that y varies inversely with x, and x = 7 and y = 4, find the value of k.

Back

k = 28.

Front

What type of variation occurs when x and y behave oppositely?

Back

Inverse variation.

Front

What is the general form of an inverse variation equation?

Back

Front

What happens to y when x increases in an inverse variation?

Back

When x increases, y decreases.

Front

What is the significance of the constant k in inverse variation?

Back

k represents the product of x and y, remaining constant.

Front

How do you determine the vertical asymptote of a rational function?

Back

The vertical asymptote is found by setting the denominator equal to zero.

Front

What is the relationship between direct variation and inverse variation?

Back

In direct variation, as one variable increases, the other also increases; in inverse variation, as one increases, the other decreases.
