Question

f(x)=10(.54)^2x
MEDAL!!!!!!!!!!
Is this equation an example of exponential decay? Explain.

Answer 1

Answer 2

Not decay, but growth. Given the typical general exponential growth/decay formula,
\[\large y=Cb^{kx}\]
the sign of \(k\) determines if the equation models growth or decay. If \(k>0\), then you have a growth model; if \(k<0\), you have decay.

Here \(k=2>0\), so you have growth.
