Question

Find the Limit, if it exist.

Lim (2X-1)/Absolute value of (2X^3 - X^2)
x-->0.5^- (from below)

Answer 1

it exists, -4.

Answer 2

i was hoping you would show me how to do it. =)

Answer 3

the easiest route would be to show that it is asymptotic at 0.5 (plug and show undef) and then you can just plug something relatively close in... 0.4999 and get -4.000something and then plug in something closer like 0.49999999 and get something like -4.00000something and show it approaches -4 in a proportional rate.

Answer 4

i have to calculate and show work.

Answer 5

plugging in values and finding what it equals is "work" its called numeric approximation.

Answer 6

ok thanks
