What is the maximum number of possible extreme values for the function,<br> f(x) = х2 -7x – 6?

timama [110]

Answer:

Only one extreme value of f(x) is possible.

Step-by-step explanation:

We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)

Now. the condition for extreme values of f(x) is $\frac{df(x)}{dx} =0$

Hence, differentiating both sides of equation (1) with respect to x, we get

$\frac{df(x)}{dx} = 2x -7$ = 0

⇒ x = 3.5.

So there is only one value of x for which f(x) has extreme value which is x = 3.5.

Therefore, only one extreme value of the given function is possible. (Answer)

$f(x) = - {x}^{3} - {x}^{2} + 1$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f( - 1) = - ({ - 1})^{3} - ({ - 1})^{2} + 1 \\$

$f( - 1) = - ( - 1) - (1) + 1$

$f( - 1) = 1 - 1 + 1$

$f( - 1) = 2 - 1$

$f( - 1) = 1$
