What is the equation that matches the function below?
You have $100 and spend $5 every week. 

• y=100^x+5
• y=5x+100
• y= -5x+100
• y = 5^x

Which function increases faster? Explain. f(x) = 4x, g(x) = 3^x

• f(x): 4 > 3 which represents the rate of growth in each function

• f(x); there is no x for which g(x) is greater than f(x)

• g(x): as x approached 8, g(x) is greater than f(x) all the way to infinity

• Neither, they increase at the same rate

On the graph y = 4^x .

What is the y-intercept?

• (0, 1)

• (0, 4)

• (0, 2)

• (0, 3)
