Answer:
Given first price: $10
New price: $12
Difference: New price - Old price
⇒ $12 - $10
⇒ $2
Now difference precentage:
(Difference÷Initial price)×100
⇒ (2 ÷ 10) × 100
⇒ 0.2 × 100
⇒ 20%
Thus the increase is by 20%

Answer:
a) Exponential decay
b,) The parent function is shifted up 1 unit.
Step-by-step explanation:
Assuming your function is

Then we can compare this to:

If

then y is an exponential decay function.
If |b|>1, then y is an exponential growth.
We can see that:

Therefore the given function is an exponential decay.
The parent function is shifted up 1 unit.
