So I'm working on Unit 2 Lesson 8: Exponents and Exponential Functions Sample Work and I cant figure out how to write why C = 535(0.90)^n r=1+(-0.10)=0.90 is exponential function and not a linear function?

1 answer

Can't figure out what
C = 535(0.90)^n r=1+(-0.10)=0.90
is supposed to be. I see 2 equal signs, so are there two equations??

anyway... , look at the term 535(.90)^t.
I see an "exponent which is a variable", so it is exponential.

To be linear, the function has a variable in the base and no exponents
other than 1.
e.g. y = 4x + 7
