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 
Hence, differentiating both sides of equation (1) with respect to x, we get
= 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)
Answer:
x= -1
Step-by-step explanation:
6-3x=5x-10x+4
6-3x=-5x+4
-4 -4
2-3x=-5x
+3x +3x
2=-2
2/-2=-2x/-2
-1=x
The answers are -16 and 9. Hopefully this helps :D
