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>

Answer:

x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}

Step-by-step explanation:

Given the equation, 3x^2 - 6x + 8 = 0, the quadratic formula for solving this equation is given as:

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Where,

a = 3

b = -6

c = 8

Plug in the above values into the quadratic formula.

x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}

x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)}
