Exponential Functions Graphing

Does the function represent exponential growth or decay?

• Decay

• Growth

Identify the horizontal asymptote of the exponential function: katex latex="y=3\left(\frac{1}{2}\right)^x"

• y=3

• y=1/2

• x=3

• y=0

Identify the y-intercept of the graph of the exponential function: y=3\left(\frac{1}{2}\right)^x

• (3,0)

• (1/2, 0)

• (0,0)

• (0,3)

Identify the horizontal asymptote for the exponential function:

• y = 0

• x = -1

• y = -1

• y = 1

• y > 1

• All real numbers

• y > -1

• x > -1

Identify the range of the exponential function.

• y > -3

• y > 5

• y < 5

• y > -5

• y > 1
