Where, we have the following variables:
x: time in seconds
y: speed in feet per seconds
For the initial velocity, we evaluate x = 0 in the given equation:

Therefore, the initial speed is 12 feet per second.
Answer:
The particle's initially velocity is 12.
APZ is the correct answer
Step 1 is correct because it is easy method to do math equations
