1250. Cubic feet = volume and volume is length * width * height. The volume of this would be 5x5x(1/2), which equals 12.5 cubic feet. 12.5*100=1250

Let f(x) = |x|, ????(x) = 2f(x), and h(x) = 1 / 2 f(x) for any real number x.

SashulF [63]

Answer:

g(x) = 2|x|

h(x) = $\frac{1}{2}$ |x|

Step-by-step explanation:

If you have g(x)=2f(x) and h(x)= $\frac{1}{2}$ f(x), you can rewrite the expressions in terms of |x| as the following:

- For g(x)=2f(x) you have:

g(x) = 2|x|

-For h(x)= $\frac{1}{2}$ f(x), you have:

h(x) = $\frac{1}{2}$ |x|

Answer:

$g\left(x\right)=-\sqrt{x+3}+8$

Step-by-step explanation:

Given function is $f\left(x\right)=-2\sqrt{x-3}+8$ .

Now let's find it's range.

we know that square root function always gives positive output then:

$\sqrt{x-3}\ge0$

$-2\sqrt{x-3}\le-2\left(0\right)$

$-2\sqrt{x-3}\le0$

$-2\sqrt{x-3}+8\le0+8$

$-2\sqrt{x-3}+8\le 8$

$f(x) \le 8$

Hence range of the function is $(-\infty,8]$ .

we can repeat same process to find the range of all the given choices.

we will find that only 3rd choice has same range.

Hence final answer is $g\left(x\right)=-\sqrt{x+3}+8$
