we have the function
\(f(x)=20(\frac{1}{4})^{x}\)
we know that
In the equation of the exponential function of the form
\(f(x)=a(b)^{x}\)
a is the initial value
b is the base
x is the exponent
The initial value is the value of the function when the value of x is equal to zero
in this problem
for \(x=0\)
\(f(0)=20(\frac{1}{4})^{0}\)
\(f(0)=20(1)=20\)
the initial value is the point \((0,20)\)
therefore
the answer in the attached figure
