Answer:
It would Be B I hope this is right
Step-by-step explanation:
Simplify both sides of the equation.

Answer: Choice D </h3>
This is another way of saying "the set of all real numbers". This is because there are no restrictions we must place on x. The graph extends infinitely in both left and right directions as the arrows indicate. Any x value can be plugged in to get some y output.
In interval notation, the domain would be written as
Answer:
-14
Step-by-step explanation:
Rewrite the equation:
-3m = 42
Next, divide both sides by -3:
-3m = 42 ---> m = -14
Last, let's make sure this is correct:
-3(-14) = 42
42 = 42 <--- This tells us it's correct
Hope this helps :)
Answer:
y = -2(x -2)^2 + 11
Step-by-step explanation:
It works well to factor the leading coefficient from the first two terms.
... y = -2(x^2 -4x) +3
Now we want to add the square of half the x-coefficient inside parentheses, and subtract the equivalent quantity outside parentheses.
... y = -2(x^2 -4x +4) +3 - (-2·4)
... y = -2(x -2)^2 +11 . . . . . . . . simplify

The form given in the problem statement is called "vertex form," where the vertex of the parabola is (h, k). A graph shows us the vertex is (2, 11), so we can write the function immediately as ...
... y = -2(x -2)^2 +11
