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
A i did this problem before with another user
The polynomial x3+8 is equal to (x+2)(x2-2x+4)
The correct answer is y=-2
I hope this helps :)
