The equation y = 210(1.094)^x depicts the amount of money in a savings account after x years. What does the y-intercept represent in the equation?

• the growth factor of the account

• the initial amount of the account

• the maximum amount of the account

• the minimum amount of the account

• The y-intercept is (0, 2000) and represents how much time it will take the laptop to depreciate to $0

• The y-intercept is (2000, 0) and represents the initial cost of the laptop.

• The y-intercept is (2000, 0) and represents how much time it will take the laptop to depreciate to $0.

• The y-intercept is (0, 2000) and represents the initial cost of the laptop.

To find the Y-intercept of a Exponential Function, we set X= 0 and solve.

• TRUE

• FALSE

Answer explanation

Given y=3^x determine the y-intercept 

• (0,1)

• (0,3)

• No Y-intercept

• y=1

Solve for the Y-intercept.

• (0, 6)

• (0, 8)

• (0, 7)

• (0, 0)
