A culture of bacteria has an initial population of 6200 bacteria and doubles every 2 hours. Using the formula
P = Po · 2á, where Pt is the population after t hours,
Po is the initial population, t is the time in hours and dis
the doubling time, what is the population of bacteria in
the culture after 7 hours, to the nearest whole number?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
