F(x)=0
f(x)=y
so where y=0, the x value is the x in f(x)
basically, where the line crosses or touches the x axis, those ar the x values that make the function true
Answer:
w=3
Step-by-step explanation:
(w+3)x2=4w
2w+6=4w
2w+6-6=4w-6
2w-4w=4w-6-4w
-2w=-6
-2w/2 = -6/2
w=3
(2,2)
(x1+x2)/2, (y1-y2)/2
(-2+6)/2=(2)
(-2+6)/2=2
