A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
Where's the digit?????????
Y = --x^2 + 1
ur whalecum :3
It's because the Y intercept is 1, so Y = mx + 1
and the line is x^2,quadratic, but going down so it is negative
