Which interval for the graphed function contains the local maximum?

Step-by-step explanation:

since maxima is a point in which a function within a range gives maximum value. And its value is called maximum value of the function over an interval.

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
