For f(-2), x will equal -2.

Plug the x-value into the equation:

[tex]2 \times 2^{-2}[/tex]

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator. 
Solve 2^(-2):

[tex]2^{-2} = \frac{1}{2^{2}} = \frac{1}{4} [/tex]

Solve the problem:

[tex]2 \times \frac{1}{4} = \frac{1}{2}[/tex]

f(-2) will equal 1/2.
