1. The graph of y = ax2 + bx + c passes through the points (1, –8), (2, –1), (3, 4), and (5, 8). If the maximum valueof y occurs at x = 5, through which other point must the graph of y pass?

• A. (4, 6)
• B. (6, 4)
• C. (8, –1)
• D. (10, –8)

2. For what values of x is the equation 2x2 = 4x + 3 true?

3. A cannonball is shot out of a cannon at a 45° angle with an approximate speed of 283m/s. The cannon from which the ball was fired sits on the edge of a cliff, and itsheight above the ground is 20 meters. The equations given above represent the cannonball'sheight above the ground (y) and its horizontal distance (x) from the face of the cliff, t seconds after it was fired, where t ≥ 0. How many seconds after the ball was fired does its vertical height above theground equal its horizontal distance from the cliff?

• A. 1
• B. 2
• C. 3
• D. 4

Gravity (m/s2)
Earth9.8
Moon1.6
Mars3.7
Venus9.5
Jupiter24.5

4. The approximate height h of an object launched vertically upward after an elapsed time t is represented by the equation, where a is acceleration due to gravity, v0 is the object's initial velocity, and h0 is the object's initial height. The table above gives the acceleration due to gravityon Earth's moon and several planets. If two identical objects are launched verticallyupward at an initial velocity of 40 m/s from the surfaces of Mars and Earth's moon,approximately how many more seconds will it take for the moon projectile to returnto the ground than the Mars projectile?
