Answer:
Step-by-step explanation:
if function is continous
lim x->0- = f(0) = lim x->o+
f(0)=t
lim x->0- (1-cos4x)/x^2
it's in 0/0 form use l hospital
lim x->0- (4sin4x)/2x
lim x->0- 8 *sin4x/4x (lim x->0 sinx/x =1)
=8
lim x->0- = f(0)
t=8
you can also check lim x->0+ rootx/root(16+rootx) -4
it will also be 8
