Question

CALCULUS LIMIT: lim x->0.5- (2x-1)/|2x^3-x^2|
I used direct substitution and gave me 0, but the answer says it's -4, why?

Answer 1

show mw your work

Answer 2

(2*0.5-1) / |2*0.5^3-0.5^2| = 0

Answer 3

the denominator is also 0, so its 0/0 not only 0

Answer 4

-(2x-1)/ x^2(2x-1)=- 1/x^2 so 1/(1/2^2)= -1/(1/4) so flip the fraction and - 4

Answer 5
