A small firm producing video games have a cost function of C(x)=20x+1000 where x is the number of games manufactured and sold. The company sells each game for $[R]. What is the minimum number of games the company must sell to break-even?

Select EACH true statement for the given function. y = 4 x 2 – 36 x 2 – 2 x – 8

Match EACH function to its graph. This should be simple if you just plot a few point. Remember; there may be some answers not used.

Consider the matrix below: 2 – 2 1 0 2 – 8 10 4 3 – 4 – 1 2  Perform the row operation : (1/2)R2⇒R2 Enter the values for A,B,C and D below: {only enter the numerical value for each. Take care not to include spaces. It will read the answer wrong if you include spaces.}   1 – 6 2 0 A B C D 3 – 4 – 1 2 A=[BLANK-1],  B=[BLANK-2],  C=[BLANK-3],  D=[BLANK-4]

Write the system as an augmented matrix.  3x-5y+z=10 2x+3y-z=-2 x+y+z=1

Give EACH value that is NOT a zero of the polynomial.x4-7×3+17×2-17x+6 

A rock is thrown upward from the top of a 112-foot high cliff overlooking the ocean at a speed of 96 feet per second. The rock’s height above ocean can be modeled by the equation h(t)=−16t2+96t+112. Do not enter units in answers. a. When does the rock reach the maximum height? Enter value for t here. t=[BLANK-1] b. What is the maximum height of the rock? Enter maximum height here. h=[BLANK-2] c. When does the rock hit the ocean? Enter value for t here. t=[BLANK-3]

How are the two functions related? f ( x ) = x – x ,             g ( x ) = – x + x

Find the difference quotient in the form of  f ( x + h ) – f ( x ) h for the function, f(x)=2×2+3x.

Given,  f ( x ) = x 2 – 9 x       a n d     g ( x ) = 3 x + 5 Find f(x3) and g(2x-1).
