Question

Find the critical numbers of the function. (Enter your answers as a comma-separated list.)

f(x) = 10x2 + 6x

Answer 1

The critical numer is x = -3/10

Explanation:

We need to find the derivative of the function and then equal to zero to get the values of x.

The function is:

`f(x)=10x^(2)+6x`

Let's take the derivative whit respect of x and equal to zero.

`f'(x)=20x+6`

`0=20x+6`

Now, we just need to solve it for x.

`x=-(3)/(10)`

The critical numer is x = -3/10
