What is the value of this limit?

lim (x^2+4/^2-3x+1)
x->4


A. 1
B. 4
C. 5
D -oo
E. oo

  • calculus -

    ***x^2-3x+1

  • calculus -

    is this

    lim (x^2 + 4)/(x^2 - 3x + 1)
    x ---> 4

    the first step in any limit is to actually sub in the approach value
    in this case we get

    lim(16+4)/(16 - 12 + 1)
    = 20/5
    = 4 , which is a real number, so we have no problem with this limit

    the answer is 4 , all done!
