Answer:

The option you chose is correct (second option)

Step-by-step explanation:

This is because since -4x is only greater than and not equal to 20, the circle should be open. Then the larges the number, the better because a negative times negative is a positive. The product of -4x has to result in something larger than 20.

Hope this helps!

What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!

Sedbober [7]

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

Plug the x-value into the equation:

$2 \times 2^{-2}$

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):

$2^{-2} = \frac{1}{2^{2}} = \frac{1}{4}$

Solve the problem:

$2 \times \frac{1}{4} = \frac{1}{2}$

f(-2) will equal 1/2.
