7.5 Graphing Exponential Functions Alg 1

On the graph y = 4^x + 2.

What is the domain?

• x > 0

• x > 2

• x > 4

• All real numbers

On the graph y = 3^x + 4 shown , what is the y=intercept?

• (0,1)

• (0,4)

• (0,5)

• There is no y-intercept

Determine the horizontal asymptote for the function

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

• x=4

• y=4

• x=5

• y=5

Write the equation of the graph.

• f(x) = 5^x + 2

• f(x) = 3^x - 2

• f(x) = 3^x + 2

• f(x) = -3^x +2

• y > 4

• y > 2

• y > 3

• y > 5
