Graph 1
Step-by-step explanation:
f(x) = __
In this equation (f(2) = 4) the 2 is the x value. All this question is asking is which graph shows a y value of 4 when x is 2.

c
Step-by-step explanation:
Answer:
A(t) = π(8t)²
Step-by-step explanation:
Radius of a circular wave increases by 8 cm each second.
Every second radius of circular wave so the sequence of increase in radius will be,
8, 16, 24, 32.........(8t)
Here 't' = time
Since, area of a circle = πr²
Therefore, area of the circular wave after 't' seconds since the wave begins,
A(t) = π(8t)²
