Algebra 2 Unit 8 Review

Mark took a loan out for $25,690 to purchase a truck. At an interest rate of 5.2% compounded monthly, how much total will he have paid after 5 years?

• $33,299.42      

• $33,672.68  

• $34,157.04        

• $34,710.88    

Determine the domain and range of the function

f(x)=-3(2)^x-4+5

• Domain: x < 4

  Range: All Real Numbers

• Domain: All Real Numbers

  Range: y > 5

• Domain: x > 4

  Range: All Real Numbers

• Domain: All Real Numbers

  Range: y < 5

2^x+6 - 3 = 29

• x=-1

• x=11

• x=1

• x=-11

Solve for x:
3^2x = 27^{x - 4}

• x = 12
• x = 4
• x = -4
• x = 1
