Does the equation x^2+y^2 represent a function with x as input and y as output? if so express the relationship as a function y=f(x)

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

i believe so, according to my "strange" way of figuring out weird math problems like this.
