Answer:
I believe it would be - (n+4) x 2
Step-by-step explanation:
The answer would be 40
-4(-2) = 8
8(5) = 40
Answer:
x = -7 and x = 3
Step-by-step explanation:
x² + 4x - 21 = 0 factors as follows: (x + 7)(x - 3) = 0.
Then x = -7 and x = 3.
Answer:
This proves that f is continous at x=5.
Step-by-step explanation:
Taking f(x) = 3x-1 and , we want to find a such that
At first, we will assume that this delta exists and we will try to figure out its value.
Suppose that . Then
.
Then, if , then . So, in this case, if we get that . The maximum value of delta is .
By definition, this procedure proves that . Note that f(5)=14, so this proves that f is continous at x=5.
