Stuck on this problem, please help

(a) -7

(b) 7

(c) DNE

Step-by-step explanation:

(a) lim f(x) x -->0-

= lim 7 (-x) / x

= -7

(b)  lim f(x) x -->0+

= lim 7y / y

= 7

(c) lim f(x) ≠ lim f(x)

≠: does not equal sign

x -->0-  ≠ x -->0+

so lim f(x) x -->0 = does not exist

look at the pictures if you don't understand

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
