ad-work [718]

Hey!

Your answers are:

- 4 less than a number

- A number decreased by 4

Let k represent "a number". "k" is a variable, and variables are unknown.

-4 is subtracting 4. That means you're subtracting 4 from a number. -4 also means that the number is decreasing by 4. Therefore, those 2 are your answers.

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

Zigmanuir [339]

Answer:

The value of f(-2) is 1/2 or it can be written as 0.5.

Step-by-step explanation:

The given function is

$f(x)=2\cdot 2^x$

We have to find the value of f(-2).

Substitute x=-2 in the given function to find the value of f(-2).

$f(-2)=2\cdot 2^(-2)$

$f(-2)=2\cdot \frac{1}{2^(2)}$

$f(-2)=\frac{1}{2}$

$f(-2)=0.5$

Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
