Step-by-step explanation:
f(x) = 2x²+8x+10
vertex point :
x = -8/2(2)= -8/4
=> x = -2 <= this is a symetry axis
f(-2)= 2(-2)²+8(-2)+10=8-16+10=2
the vertex point : (-2, 2)
intercept with y-axis :
f(0) = 0+0+10 = 10
the point : (0, 10)
the drawing as attached
The airplane takes off 12 1/2 miles south of a city
Speed =180*3/4
=45*3
=135
135-12.5
The plane is 122.5 miles north to the city after 45 minutes
