lg y = (b + x) lg a
lg y = (lg a) x + b lg a
The (b + x) comes down together as a bracket
lg y = (lg a) x + b lg a
The (b + x) comes down together as a bracket
Ohhh. I see now, thank you!
The other way to get to the equation :
lg y = lg a^(b+x)
lg y = lg (a^b a^x)
lg y = lg a^b + lg a^x
lg y = lg a^b + x lga
Rewrite as lg y = lga x + lg a^b
Compare this to Y = mX + C
lg y = lg a^(b+x)
lg y = lg (a^b a^x)
lg y = lg a^b + lg a^x
lg y = lg a^b + x lga
Rewrite as lg y = lga x + lg a^b
Compare this to Y = mX + C
