y=(x+4)(x-2)
to find the x intercept put y=0
0=(x+4)(x-2)
so either x=-4 or x=2
Therefore the graph intersects the x axis at -4 and 2
Lenght of x intercept=|-4-2|=6 units
y=(x+4)(x-2)
=x^2+2x-8
This is an upward opening parabola
To find the coordinates of the vertex we can apply the formula
(-b/2a,-D/4a)
b=2
a=1
D=b^2-4ac
=4-4*1*(-8)
=4+32=36
Vertex=(-2/2*1,-36/4*1)
=(-1,-9)
Hope this helps.

Answer:
Step-by-step explanation:
the passengers of hawaiian airlines in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)
We replace this number in the equation :
Hawaiian : 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (1.800.000) =12294012
Northwest airlines: 0,990 +0.683 x (number of passengers) =
0.990 + 0.683 x (195.000.000) = 131477501
