Is the equation y = 5(0.5)x an example of growth or decay?

    What's going on with y as x keeps getting bigger?

    Why growth?\[0.05^2 <0.05^1 \]That proves that it's decay itself.

    If the second power is less than the first, then we have an exponential decay. Get it?

    Yes, I believe the OP means raised to the power of x. Not linear in x.

    if its a raised power then may be its decay

    @Hashir The question is\[5 \times 0.5^x\]

    Well, if its raised to x, its DEFINITELY decay, not maybe.

    so if the number in the parentheses is lower then 1 its decay

    When people copy and paste questions, they don't type out ^ before powers.

    \[y(x) = 5(0.5)^x\] lets try some points \[y(0) = 5(0.5)^0=5\] \[y(1) = 5(0.5)^1=5\times0.5=2.5\] \[y(2) = 5(0.5)^2=5\times0.25=1.25\] as x goes up y decreases , decay
