Determine if the equation y = 3(3.4)x represents exponential growth or decay.
This is exponential growth. it would have been decay if x was negative
this is \[y=3(3.4)^x\] and you have to notice that \[3.4>1\] so see it is growth
@mohammad, x is a variable so it can be positive or negative
Oh yes. sorry my mistake
