Pls awsner this question for math2

In functions for every x corresponds with only one y.

In given example if x=0, it gives you 2 valus.

So this is not a function.

This is an equation of a circle with starting point (0;0) and Radius of 4;

+ the equation is x^2 + y^2 = R^2.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5
