Question

Graph the function f(x) = (x + 3)^3 by hand and describe the end behavior.

Answer 1

plug in really really big positive number for x and see what happen

plug in really really big neagive number for x and see what happen

Answer 2

what do u mean

Answer 3

just plug in a number which tends to positive and negative infinity to see what the function behaves as at the end points... for eg. if u plug a really big positive number as imran says u will see that the fubction tends to +∞

Answer 4

ok and then what

Answer 5

similarly if u see it at -∞ it again tends to -∞ , so you can describe the function at the end as ut tends to positive as x tends infinity and negative infinity when x tends to negative infinity.. It was simpler in this case, sometimes becomes difficult when function is confusing is how ur graph looks
