Example Question #81 : Solving And Graphing Logarithms

Give the equation of the horizontal asymptote of the graph of the equation 

.

Possible Answers:

The graph of  does not have a horizontal asymptote.

Correct answer:

The graph of  does not have a horizontal asymptote.

Explanation:

Let 

 In terms of ,

This is the graph of  shifted left 4 units, stretched vertically by a factor of 3, then shifted up 2 units. 

The graph of  does not have a horizontal asymptote; therefore, a transformation of this graph, such as that of , does not have a horizontal asymptote either.

Example Question #7 : Graphing Logarithmic Functions

Find the equation of the vertical asymptote of the graph of the equation 

.

Possible Answers:

Correct answer:

Explanation:

Let . In terms of ,

.

The graph of  has as its vertical asymptote the line of the equation . The graph of  is the result of three transformations on the graph of - a left shift of 4 units , a vertical stretch (  ), and an upward shift of 2 units (  ). Of the three transformations, only the left shift affects the position of the vertical asymptote - the asymptote of  also shifts left 4 units, to .

Example Question #1 : Negative Exponents

Represent the fraction using only positive exponents:

Possible Answers:

Correct answer:

Explanation:

Negative exponents are the reciprocal of their positive counterpart. For example:

Therefore:

This simplifies to:

Example Question #7 : Negative Exponents

Solve the equation for n:

Possible Answers:

Correct answer:

Explanation:

Rewrite the right-hand-side so that each side has the same base:

Use the Property of Equality for Exponential Functions:

Solving for :

 

Example Question #2 : Negative Exponents

What is  the same as?

Possible Answers:

Correct answer:

Explanation:

While a positive exponent says how many times to multiply by a number, a negative exponent says how many times to divide by the number.

To solve for negative exponents, just calculate the reciprocal.
