Exponential Practice

Which type of function is represented in the graph?Which equation could match the graph shown?

A table whose y-column changes by a constant ratio is

• exponential

• linear

• neither

The graph of a function that is curved is

• exponential

• linear

• neither

In the equation y=a(b)^x, the letter "a" represents

• total

• slope (constant ratio)

• time

• y-intercept/starting point

In the equation y=a(b)^x, the letter "b" represents

• total

• rate of change (constant ratio)

• time

• y-intercept/starting point
