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

What is the horizontal asymptote?

• y = 2
• y = -2
• x = 2
• y = 0

What transformations occur to f(x)=5^x?

• translate right 3, up 2

• translate left 3, up 2

• translate left 3, down 2

• translate right 3, down 2

What transformations have happened to f(x) = 2^x if the new equation is
 g(x) = -2^(x+3) -6

• It stayed the same
• reflects, up 3, left 6
• reflects, right 3, down 6
• reflects, left 3, down 6

The growth factor for this table is 

• 2
• 4
• 12
• 144

The equation for this table is 

• y = 1(2^x)
• y = 1(12^x)
• y = 12x
• y = 12x + 1

• 2
• 4
• (2)^x
• 8

• right 7, up 10

• left 7, down 10

• right 7, down 10

• left 7, up 10
