Solution:
f(x) is denoted for any function where x is any input value.
From the given data,
f(x) = 2 × (2 x) --------(1)
where x is an input value.
To find the value of f(-2), we need to substitute x as -2 in equation (1)
Hence, f(-2) = 2 × [2 × (-2)]
On simplifying, we get f(-2) = -8
Therefore, the value of f(x) = 2 • 2 x for f(-2) is -8.
Summary:
The value of f(x) = 2 • 2 x for f(-2) is -8.
