y = -4x2 - 16x - 11
you can try to factor it or use the quadratic formula:
x = (-b + (b2-4ac)1/2)/(2a)
x = (-b - (b2-4ac)1/2)/(2a)
so...
x = (16 +/- (162- (4*-4*-11))1/2)/(2*-4)
x = (16 +/- (80)1/2)/-8
in decimals, you have:
x = (16+8.944)/-8 = -3.118
x = (16-8.944)/-8 = -0.882

a = 3 and y = 0
y=9x=3it equals ......y= 3.334
The y-intercept equals 0.
y=10
Transitive property: If 8 equals x and x equals y, then 8 equals y.
