6.3-6.5 Review

What is the domain and range of the function y=2^x ?
Use the graph to help!

•  Domain: −∞<x<∞ Range: y>0

• Domain: −∞<x<∞ Range: y>1

• Domain: −2<x<∞ Range: y>0

• Domain: −∞>x>∞ Range: y>0

Is the pictured graph exponential growth, exponential decay, linear or none?

• Exponential Growth

• Exponential Decay

• Linear

• None

Given y = 3^x determine the y-intercept 

• (0,1)

• (0,3)

• No Y-intercept

• y=1

What function is present? 

• Absolute Value
• Exponential Decay
• Linear Equation
• Exponential Growth

Solve: 2^x = 4^x+1

• x = -2
• x = 2
• x = -3
• x = 3

Solve: 9^8-x = 27^x-3

• x = 5
• x = -5
• x = 1/5
• x = -1/5

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

• x = 12
• x = 4
• x = -4
• x = 1

Solve for x:
9^x+8 = 81

• 2
• -6
• 6
• 8

2^-m = 2^3m-3

• 4/3
• 3/4
• 2
