Question

how do i find the lim (X^2+3x) analytically?
X->-3

Answer 1

replace x by -3 in your expression

Answer 2

i get lim =0 but when i graph the point -3 isnt at 0

Answer 3

instead the parabola is (-3,18)

Answer 4

(-3)^2+3(-3)=9+-9=0

Answer 5

yes i got that but as X aproaches -3, 0 isnt a y coordinate on the porabola.

yes it is
