## Transcribed Text

1. Solve the system using Gauss-Jordan elimination, i.e. place in row reduced echelon form. 1. Solve the following system. 2x+3y = 9 Follow the given directions: 1a 1y = 2 Step 1: Place in augmented matrix form. Step 2: R1 - Rg Step 3: 2R1 + R2 - Rg Step 4: - Rg Step 5: R2 + R1 - R1 Step 6: Write your solution as an ordered pair. ( , ). Check your solution. 2. Solve the system by graphing, then check your work algebraically. .x -2y+4=0 (4y=r² 3. Solve the following and check your solutions. a- 6=- = 36 b. log 3z-1 = 2r+3 0 C. log4(x - 4) + log4(x - 16) = log464 4. Graph the following pair of functions. Label units. Determine the D, R, intercepts, and intervals of behavior for all the graphs. Determine any asymptotes, where appropriate. a. fi(x) z3 and D1 {x| } R1-{y| } D2 {x1 ] R2- yyl } b. fi(x) : D1 {x| }RR-\y\ } D2 {x1 } c. fi(x) - 3° and it's inverse. What is the inverse function? D1 {x| } R1 {y| } Dr {x1 } Ra {ul } d. fi(x) - 22and f2(x) - 21-r+3 D1 {x| } R1 {y| } D2 {x } c. f1(x) - 1 and it's inverse. What is the equation for the inverse?
