The required value of f(3) = 49.
f(x)= (1/7)(7^x)
what is exponential function?
The function which is in format f(x) = where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
f(x)= (1/7)(7^x)
f(3) = 1/7(7^3)
f(3) = 1/7 x 7³
f(3) = 7² = 49
Thus the required value for f(3) = 49
