Identify the vertex, the axis of symmetry, the maximum or minimum value, and the domain and range of the function. f(x)= -(x - 9)2 - 23

Yes you are correct

Ithink it is 7. 16

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
