Question

which one or ones of the follwoing statements are true?
1. if the line y=2 is ahorizontal asymptote of y=f(x0, then f is not defined at y=2
ii. if f(1)>0 and f93)<0, then there exists a number 1 and 3 such that f(c0 =0
iii. if f is continuous at x=6 and f(6)=8 and f(4)=2, then limit of f(4x^2-10)= 8 as x approaches 2

Answer 1

I think 3 part is correct
