The solution for this problem would be:
f'(x) = 1 - 1/x^2 = (x^2 - 1)/x^2
is positive where |x| > 1
hence (-inf, -1) and (1, inf) are the regions in which f' is positive and therefore f is increasing.
Therefore, the answer is (-infinity,-1] U [1,infinity).
Answer:
i don't know exactly.
Step-by-step explanation:
but the might be an angle tool online.
I can’t solve all of them but maybe one and I will give you the formula for you to solve the rest.
Slope = (y2 -y1) / (x2 -x1).
m= ( 16 -(-3)) / ( -14 -(-9))
m = (16+3)/(-14+9)
m = 19/ -5
2 x -6 equals 0. add 6 to both sides. divide both sides by two. x equals 3
Answer:
A dashed line
Step-by-step explanation:
The end points of the line for the inequality would not be included since y is only greater, not greater than or equal to.
