Function f(x) = (4)ˣ is increasing which is correct option (C).
What is function?
The function is defined as mathematics expression defines a relationship between one variable and another variable.
Substitute x = 1 in all the options
f(x) = (0.4)ˣ ⇒ f(1) = 0.4
f(x) = (1/2)ˣ ⇒ f(1) = 1/2
f(x) = (4)ˣ ⇒ f(1) = 4
f(x) = (1/4)ˣ ⇒ f(1) = 1/4
So, Clearly value of f(x) = (4)ˣ is getting larger than as compare to other options
Hence, function f(x) = (4)ˣ is increasing.
