Where do logarithmic graphs come from

The video tutorial introduces logarithmic graphs by explaining their relationship with exponential graphs. It covers the properties and transformations of exponential graphs, the concept of inverse functions, and how logarithms are formed. The tutorial also demonstrates graphing logarithmic functions and compares them to exponential functions, highlighting key features such as asymptotes, domain, and range. The session concludes with a summary of the transition from exponential to logarithmic functions.

What is the y-intercept of an exponential graph with the equation y = a^x?

• 0, 0

• 1, a

• 0, 1

• 1, 0

How do you find the inverse of an exponential function?

• Swap the domain and range

• Swap the x and y variables

• Swap the coefficients

• Swap the base and the exponent

What is the relationship between an exponential function and its logarithmic inverse?

• They are reflections over the line y = x

• They are inverses with no graphical relationship

• They are reflections over the y-axis

• They are identical

Which point is on the graph of a logarithmic function if the corresponding exponential function has a point at (0, 1)?

• (1, 1)

• (a, 1)

• (0, 0)

• (1, 0)

What is the asymptote of an exponential function?

• x = 0

• y = 1

• y = 0

• x = 1

What is the domain of a logarithmic function?

• All real numbers

• Negative infinity to zero

• Zero to infinity

• Negative infinity to positive infinity

What is the range of a logarithmic function?

• Negative infinity to infinity

• Zero to infinity

• Zero to one

• Negative infinity to zero
