Question 321999
If f(x) = 4x - 2 and g(x) = 3x. What is f(g(2))? I got 22 
{{{g(x)=3x}}}
{{{g(2)=3(2)=6}}}
{{{f(x)=4x-2}}}
{{{f(g(2))=f(6)=4(6)-2=24-2=22}}}
Yes, that's correct.

.
. 
{{{t(y) = y^3 + 64}}}
{{{t(-4)=(-4)^3+64=-64+64=0}}}
.
.
.
{{{f(x) = x-2}}}
{{{f(x+1)=(x+1)-2=x-1}}}
{{{f(3x)=3x-2}}}
Find x when
{{{x-1=3x-2}}}
{{{2x=1}}}
{{{x=1/2}}}
.
.
.
Verifying the solution.
{{{f(x+1)=f(1/2+1)=f(3/2)}}}
{{{f(3x)=f(3(1/2))=f(3/2)}}}
So 
{{{f(x+1)=f(3x)}}}
