LHS=18-3(2p+4)
=18-6p-12
=6-6p
=3(2-2P) hence it is not equal to 3(2-3p)
1.The sample is biased because it does not represent the population.
2.The question is biased toward a Yes response.

Answer: 
Step-by-step explanation:
Let the given parabolic mirror opens upwards and vertex=(0,0)
Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2
Since, the parabola opens upward, then the equation of the parabola is of the form 
Substitute the value of p=2 in this, we get the equation of the parabolic mirror

Hence, the equation of the parabola that models the cross section of the mirror is
