Find the x-intercepts and y-intercept for the parabola below. write answers as (x, y) coordinates. y=2x2-4x-6 x-int: y-int:

Assuming the function is
the x intercepts are where the graph hits the x axis or where y=0
the y intercepts are where the graph hits the y axis or where x=0

x intercepts
set y=0 and find x


what 2 numbers multiply to get -3 and add to get -2?
-3 and 1

set to 0
0=x-3
3=x
0=x+1
-1=x

x intercepts are at x=-1 and 3 or the points (-1,0) and (3,0)

y intercepts are where x=0
set x=0



y intercept is at (0,-6)

x intercepts are at (-1,0) and (3,0)
y intercept is at (0,-6)
