anonymous · Answer

is y=112(1.320) the complete question? is there an exponent?

anonymous · Answer

yes its the question @090909090909  no there is an x at the end where the exponent should be but it's not a number

anonymous · Answer

so it is $$y = 112(1.320)^x$$

anonymous · Answer

................yes

anonymous · Answer

to tell if it is growth or decay, look at the number in the parentheses that is being raised to x.

anonymous · Answer

if that number is between 0 and 1 it is decay, if it is greater than 1 it is growth. so what would it be?

anonymous · Answer

growth

anonymous · Answer

correct :)
