how did u get the
limit(x->2-, f(x))
and
limit(x->2+, f(x))
?

[simple forge]

I used this one and replace x

i think cuz i was doing everything on calc

[azure shuttle]

oh wait it's -2 I thought it's 2 😅

1. -7M - 7 = 2(-7) - 1
   -7M - 7 = -15
   -7M = -8
   M = 8/7
   lim(x->-7, f(x)) = -15

[simple forge]

got it

2. 2(3) - 1 = (1/3)(3) + B
   5 = 1 + B
   B = 4
   lim(x->3, f(x)) = 5

[simple forge]

B=4 how?

1+3?

1B+3*?

[azure shuttle]

B = 5 - 1

[simple forge]

understand
