• $2f\left(x\right)$
  

• $\frac{1}{2}f\left(x-1\right)-1$

• $2f\left(x+1\right)$

The height, h, in feet, of an object thrown upward from a height of 144 feet is a function of time, t, in seconds. The height can be determined by the function  $h\left(t\right)=-16t^2+128t+144$  .  

What is the height of the object at 3 seconds.

• 144

• 384

• 432

In 1997 there were 31 laptop computers at Grove High School. Starting in 1998 the school bought 20 more laptop computers at the end of each year. The equation

T=20x+31 can be used to determine T, the total number of laptop computers at the school x years after 1997. What was the total number of laptop computers at Grove High School at the end of 2005?

• 160

• 171

• 191

• 268

The number of miles a car can be driven depends on the number of gallons of gas in its tank. The function m=25g models a situation in which a car gets 25 miles per gallon. If the gas tank holds 20 gallons of gas, which inequality represents its range?

• $0\le x\le20$

• $0\le m\le500$

• $m\le500$

• $g\le20$

Which equation could best be used to determine the value of f (3) for the function f(x) = 2x+4?

• $f\left(3\right)=23+4$

• $f\left(3\right)=2\left(3\right)+4$

• $f\left(3\right)=3\left(2x\right)+4$

• $f\left(3\right)=3\left(3x+4\right)$

Vincent goes to the gym for 30 minutes every day. He starts a new exercise routine on a Monday and uses a function to model the amount of calories he has used, f(d), as a function of the number of days, d, he has exercised with the new routine. Which statement represents a correct interpretation of f(d)?

• f(5) = 150 means Vincent has exercised for a total of 150 minutes after the fifth day of exercising with his new routine.

• f(10) = 3,500 means Vincent will use 3,500 calories on day 10 of exercising with his new routine.

• f(15) = 5,250 means after 15 days of exercising with his new routine, Vincent has used 5,250 calories.

• f(30) = 10,500 means the number of calories Vincent has used times 30 is equal to 10,500.
