Help with num 9 please. thanks​
Alik [6]

Answer:

See Below.

Step-by-step explanation:

We want to show that the function:

f(x) = e^x - e^{-x}

Increases for all values of <em>x</em>.

A function is increasing whenever its derivative is positive.

So, find the derivative of our function:

\displaystyle f'(x) = \frac{d}{dx}\left[e^x - e^{-x}\right]

Differentiate:

\displaystyle f'(x) = e^x - (-e^{-x})

Simplify:

f'(x) = e^x+e^{-x}

Since eˣ is always greater than zero and e⁻ˣ is also always greater than zero, f'(x) is always positive. Hence, the original function increases for all values of <em>x.</em>

Each face of a cube has an area of 16 inches squared what is the volume of the cube
lakkis [162]

Answer:

64 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the length of the side )

Given

area = 16, then

s² = 16 ( take the square root of both sides )

s = \sqrt{16} = 4 , thus

V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
