A 12 foot long wooden beam is supported on both ends.  When a weight load is placed in the center of the beam, it causes the beam to sag.  The sag is called deflection.  The graph shows the deflection of the beam, in inches, as a deflection of the weight load, in pounds, placed in the center of the beam.

For every 50-pound increase in the weight load, what will be the change in deflection?
A.)  an increase of 0.5 inch
B.)  a decrease of 0.5 inch
C.)  an increase of 0.25 inch
​D.)  a decrease of 0.25 inch

A company has developed a new video game console.  After completing cost analysis and demand forecasts, the company has determined that the profit function for the new console is f(g) = -250g² + 70,000g - 4,570,000,
​ where g is the number of consoles sold.  What is the domain of the profit function?
A.)  all integers
B.)  all rational numbers
C.)  all integers greater than or equal to 0
D.)  all rational numbers greater than or equal to 0

The function f is defined as f(x) = x(x² - 4) - 3x(x - 2).

Indicate all zeros.
A.)  -12       
B.)  -6
C.)  -3
D.)  -2
E.)  0
F.)  2
G.)  6
H.)  12
