What is the value of f(x) = 2 • 2 x for f(-2)?

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.

What is the value of f(x) = 2 • 2 x for f(-2)?

Summary:

The value of f(x) = 2 • 2 x for f(-2) is -8.
