Which quadratic has a maximum? a. y = x2 + 2x + 2
b. y = - 2x² – 3x + 5
c. y = 0.5(x – 3)2 + 1
d. y = 2x + x2 - 1

b. y = - 2x² – 3x + 5

Step-by-step explanation:

If you check on a graphing calculator or desmos, you will see that the parabola opens down, so there is a highest point, or a maximum. You can also know that without a calculator by looking at the sign in front of x. Since answer choice b is the only one with a negative in front (meaning that the parabola opens down giving you a maximum) then you will know that that's the correct answer.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
