Not sure about remainder theorem but I'm sure that the last terms should all multiply tho the last term

see the expanded form is -45

so the last terms of each binomial should multiply to -45

3 times -5 times ?=-45
-15 times ?=-45
divide by -15
?=3

the question mark is 3

Answer:

y = -(x+1)^2 +3

Step-by-step explanation:

Translating f(x) left by 1 unit replaces x with x+1.

Translating f(x) up by 3 units replaces f(x) with f(x)+3.

Reflecting f(x) over the x-axis replaces f(x) with -f(x).

When y = x^2 is reflected over the x-axis, it becomes ...

y = -x^2

When y = -x^2 is translated 1 unit left, it becomes ...

y = -(x +1)^2

When y = -(x+1)^2 is translated 3 units up, it becomes ...

y = -(x +1)^2 +3
