Linear vs Exponential Functions

What is the equation for this graph?

• y=2(5)^x

• y=2(4)^x

• y=3(2)^x

• y=2(3)^x

Which of the following is an exponential function whose y-intercept is 50?

• y = 50x(.05)²

• y = 50x - 4

• y = (2)^x + 50

• y = 50(1.4)^x

Write the exponential equation that represents the given table. HINT: To find the y-intercept, use the common ratio to calculate the y-value when x = 0.
