What’s the derivative of the function: A) f(x)= 1/x , in point 2. B) f(x)= 5x^2 , in point 3
bija089 [108]

Using the power rule, the derivatives are given as follows:

a) f^{\prime}(2) = -\frac{1}{4}.

b) f^{\prime}(3) = 30.

<h3>What is the power rule for a derivative?</h3>

Suppose we have a power function given by:

f(x) = x^n

The derivative of the function is given by:

f^{\prime}(x) = n \times x^{n-1}

Item a:

The function is:

f(x) = \frac{1}{x} = x^{-1}

Then the derivative is:

f^{\prime}(x) = -x^{-2} = -\frac{1}{x^2}

When x = 2, the derivative is:

f^{\prime}(2) = -\frac{1}{4}

Item b:

The function is:

f(x) = 5x^2

Then the derivative is:

f^{\prime}(x) = 10x

When x = 3, the derivative is:

f^{\prime}(3) = 30

A population of 249 birds increases at a rate of 16% annually. jewel writes and exponential function of the form f(x)=abc to rep
Ad libitum [116K]

Answer:

a = 249 and b = 1.16

Step-by-step explanation:

Consider the provided information.

The exponential function for growth is:  y=a(1+ r)^x

Here, a is the initial value and r is the rate of change.

It is given that the number of birds is 249.

It means a = 249

The rate is given 16%

r=0.16

Put the value of a and r in the above formula.

y=249(1+0.16)^x

y=249(1.16)^x

Now we will compare it with the exponential function form y=ab^x

Therefore, a = 249 and b = 1.16
