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

3. ParthKohli Group Title

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

4. ParthKohli Group Title

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

5. qpHalcy0n Group Title

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

7. Hashir Group Title

if its a raised power then may be its decay

8. ParthKohli Group Title

@Hashir The question is$5 \times 0.5^x$

9. qpHalcy0n Group Title

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

10. greener6 Group Title

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

13. ParthKohli Group Title

Yes @greener6
