How can I determine if two log functions are equivalent?

Click For Summary
SUMMARY

The discussion centers on determining the equivalence of two logarithmic functions: Y1 = log(X^26) and Y2 = 26 log(X). The user graphed these functions using X values ranging from -5 to 5 but struggled to interpret the results. Key logarithmic properties, such as log(AB) = log(A) + log(B), are highlighted as essential for understanding the relationship between these functions. The conclusion is that Y1 and Y2 are indeed equivalent for positive values of X, as they simplify to the same expression.

PREREQUISITES
  • Understanding of logarithmic properties, specifically log(AB) = log(A) + log(B)
  • Basic graphing skills to visualize functions
  • Familiarity with the concept of function equivalence
  • Knowledge of domain restrictions for logarithmic functions
NEXT STEPS
  • Study the properties of logarithms in depth, including change of base and product rules
  • Learn how to graph logarithmic functions effectively using tools like Desmos or GeoGebra
  • Explore the concept of function equivalence and transformations in algebra
  • Investigate the domain and range of logarithmic functions to understand their limitations
USEFUL FOR

Students, educators, and anyone interested in mastering logarithmic functions and their properties, particularly in algebra and calculus contexts.

Graph Y1 = log (X^26) & Y2 = 26 Log (X) Are they Equivalent ?

I drew the graph using X values ( -5, -4, -3, ... , 4, 5 )
and I got graphs, but don't know how to account for any differences in two functions..
Can anyone in here help

When working with logs, you should know that,

log(AB) = log(A) + log(B)

What does that tell you about,
log(AA) = ??

what about.
log(AAA) = ?

etc.
 
Why not show us your table of values?
