I keep getting the wrong answer thanks
original equation : log base 4(x)
new equation f(x) = -log base 4 (x-3)

for example i keep getting getting reflection along the y axis and horizontal shift left 3 units
2007-02-24 17:03:42 · update #1
y = log base 4(x)
u = 4^y
v = u-3
w = log base 4(v)
f = -w

I'm not sure I understand your question. Log base 4 x and you have a new equation but also in base 4. What are you trying to transform?

multiplying by a -1 reflects the graph about the x axis
(x-3) gives you a right shift of 3.
The graph of -log4(x-3) is the graph of log4(x) shifted to the right 3 units and reflected about the x axis
-f(x) is a reflection about the x axis
f(-x) is a reflection about the y axis
f(x+a) is a left shift by a units
f(x-a) is a right shift by a units
