7.1 Nonlinear Extra Practice

What is the b in this equation called?

• Starting Value

• Multiplier

• Common Difference

Choose the exponential equation with a starting value at 6 and a multiplier of 1.8

• y = 6(1.8)^x

• y = 1.8(6)^x

• y = 6(0.18)^x

What is the starting number?

What is the multiplier?

What is the growth rate?

What is the starting value?

What is the multiplier?

What is the decay rate?

A 100 gram sample of a radioactive isotope decays exponentially at a rate of 6% every week.

Write an equation to model the situation.

• y=100(0.06)^x

• y=100(0.94)^x

• y=100(0.6)^x

• y=6(100)^x

How much of the isotope will remain after 26 weeks?
