1.a. (3 marks)

where a is non-zero constant. show that a stretch scale factor 3√a parallel to the x-axis transforms the curve y=f(x) onto the curve y=g(x) where

1.b. (3 marks) hence find the solutions to f(x) =0, giving your answers in terms of a.

honestly algebra confuses me so much that i have no way to answer .

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

i'll be glad to : )
