Look at the equations and graphs above. By looking at an exponential equation, how can you tell if the equation is exponential growth or exponential decay? Questions 8-13: write whether the exponential equation is growth or decay (or neither): 8. y = 4(0.9) * 9. y = 1(1.5)* 11. 2.2* 10. y = 0.5(3)* 12. y = 100(0.5)* 13. y= 8(1)*
