Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.
Citrus2011 [14]

Answer:

f'(x)=-5ae^{ax}=a f(x), where a be a constant.

Step-by-step explanation:

Note: The given functions is a constant function because variable term is missing.

Consider the given function is

f(x)=-5e^{ax}

where a be a constant.

We need to find the derivative of the function.

Differentiate with respect to x.

f'(x)=\dfrac{d}{dx}(-5e^{ax})

f'(x)=-5\dfrac{d}{dx}(e^{ax})

f'(x)=-5e^{ax}\dfrac{d}{dx}(ax)            [\because \dfrac{d}{dx}(e^x)=e^x]

f'(x)=-5ae^{ax}

f'(x)=a(-5e^{ax})

f'(x)=a f(x)

Therefore, the derivative of the function is f'(x)=-5ae^{ax}=a f(x).

Use the quadratic formula to solve the equation -3x2-x-3=0
Novosadov [1.4K]

Answer:

x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\

Step-by-step explanation:

the quadratic formula is:

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

a= -2, b = -1 and c =-3

Putting values in the formula

x=\frac{-(-1)\pm\sqrt{(-1)^2-4(-3)(-3)}}{2(-3)}\\x=\frac{1\pm\sqrt{-35}}{-6}\\x=\frac{1+\sqrt{-35}}{-6}\,\, and\,\, x=\frac{1-\sqrt{-35}}{-6}\\We\,\, know \,\,that \,\,\sqrt{-1} = i  \\x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\

So, x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\
