Question

Find the value of x for which
f(x) = x - 6x + 12x + 10 is increasing.

Answer 1

Step-by-step explanation:

$f(x) = x - 6x + 12x + 10 \\ x - 6x + 12x + 10 = 0 \\ 13x - 6x + 10 = 0 \\ 7x + 10 = 0 \\ 7x = - 10 \\ x = \frac{ - 10}{7}$

I hope it helps you

Answer 2

The value of x is no specific for which the function is icreasing as it is always increasing for any value of x.

To find the values of x for which the function f(x) is increasing, we need to find the first derivative of the function and check where it is positive.

The first derivative of the function f(x) is:

f'(x) = 1 - 6 + 12

Simplifying this expression, we get:

f'(x) = 7

Since f'(x) is a constant (7), it is always positive. Therefore, the function f(x) is increasing for all values of x.

So there is no specific value of x for which the function is increasing, as it is always increasing for any value of x.
