2(x-3)5x = 5(2x6)
2(x-3)5x = 60
2x -6 x 5x = 60
2x -30x = 60
-28x = 60
28x = -60
x = -15/7
Not sure if I'm correct, but hope it helped
Answer with Step-by-step explanation:
We are given that a function f(x) is continuous on ().
1.f'(-1)=0 and f''(-1)=-7
We have to find information about f.
When f'(-1)=0 and f''(-1)=-7 < 0
Then, function is maximum at x=-1.
Therefore, at x=-1, f has local maximum.
Answer:a)at x=-1 ,f has local maximum.
2.) if f'(4)=0 and f''(4)=0
We know that when f''(x)=0 then test fails then the function has not maximum or minimum.
Therefore, at x=4 , f has not a maximum or minimum.
Answer:c) at x=4, f has not a maximum or minimum.
Answer:
The quadratic formuls that this graph represents is: <u><em>f (x) = -x 2 -2x +3</em></u>
Have a nice day!
Answer:
c < 4
Step-by-step explanation:
whenever you divide or multiply an inequality by a negative it is a rule that you must reverse the inequality symbol
so -c > -4 means you must divide or multiply by a negative one to get 'c' by itself; therefore it becomes c < 4
