Can somebody please help me?

Evaluate the expression. (9 + 5)(3 + 2)0

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number?

If you double the input of a function and it results in half the output, and if you triple the input and it results in a third of the output, what can be guessed about the function? check all that apply.
