Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k. A) 2 B) 3 C) 4 D) 5 IF YOU ANSWER IN 5 MINUTES I WILL GIVE BRAINLIEST

Ans   k = 4

Step-by-step explanation:

Here g(x) = and

        f(x) =

Now,  g(x) = f(x) + k

    or,        =  

    or,      1 + 3 = k

    So,  k = 4   Answer.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
