A bird dove towards a lake, touched it briefly to grab a fish, and then flew off into the air. The graph below shows the bird's height relative to the surface of the water over time, where the bird's height (y) is measured in meters and time (x) is measured in seconds.
After how many seconds did the bird hit the water?
Your

seconds

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
