Which of the following is the formula in solving finite geometric series. Sₙ = a₁(1+rⁿ)/ (1-r) Sₙ = a₁(1-rⁿ)/ (r-1) Sₙ = a₁(1-rⁿ)/ (1-r) Sₙ = a₁(1-rⁿ)/ (1+r)

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.
