The excluded values of a rational expression are 2 and 5. Which of the following could be this expression?
muminat
<span>You have not added the options, therefore, I cannot provide an exact answer. However, I can help you with the concept.

In any fraction, the <u>denominator cannot be equal to zero</u> because this would make the fraction <u>undefined</u>.
<u>Excluded values</u> are the values that would make the denominator equal to zero.

We are given that the excluded values are 2 and 5, this means that the factors of the denominator are (x-2) and (x-5)
This means that the denominator is x</span>²<span> - 7x + 10

Pick the fraction which has this denominator.

Hope this helps :)</span>

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
