Question

Select "Yes" or "No" to indicate whether the ordered pair is on the graph of the function f(x)=−9^x+1 .

Answer 1

I'm assuming your function is f(x) = -9^(x+1)
So we just have to plug in and see if the function is true.

1) -9^(0+1) = -9^1 = -9
YES

2) -9^(1+1) = -9^2 = -81
NO

3) -9^(-1+1) = -9^0 = -1
YES
