Question 993481: Given the function
y = ( x+3 ) ( x^2+3 x−3 )
find the coordinates of the points of intersection with the x-axis and y-axis.
Please enter your answer as a set of coordinate pairs, where a single coordinate pair (a, b)
constants should all be given exactly, using the sqrt function and fractions as necessary
THANK YOU

You can put this solution on YOUR website! 
intersection with the x-axis occurs where 
and
intersection with the y-axis occurs where 
so set and find intersection with the x-axis
 ...will be true for  or  , or both
if =>
...use quadratic formula
solutions: exact solutions
or
approximate solutions:
or
so, ordered pairs are:
( , )
( ,)
( ,)
or
(,)
( ,)
( ,)
now find y-intercept:
the y-axis occurs where , so set
ordered pair is:
( , )
see it on the graph:
