Does y=432(1.54) represent growth or decay? and what is the percent of increase or decrease? i need understanding what i need to do?

anyhow, the flag is that 1.54 is "more" than 1, thus is growth.

if it were decay, then the rate gets subtracted, and it be (1 - r), and the flag for a decay is that the value in the parentheses is less than 1, like say  432(0.95)ᵗ, since 0.95 is really just 1 - 0.05, then r = 0.05 or 0.05 * 100 or 5%.
