1. b
2. x=-2
3. b
4. (-7, 3)
5. (-2, 2)(1, -1)(3, 1)(2,4)
<span>g(x) = x^2 + 3x - 4 (please be sure to use " ^ " to denote exponentiation).
This function factors into g(x) = (x+4)(x-1), and so the zeros are -4 and +1.
If we shift this graph 5 units to the left, we get h(x) = (x+5)^2 + 3(x+5) - 4.
The new zeros will be -4-5 and 1-5, or -9 and -4.

Answer and Step-by-step explanation:
The step that was wrong is at C: when Jennifer added the 1 into the parentheses, she forgot to subtract 1 from the 7. The reason she needs to do that is because now, if you compare her equation at C with her original, they're not the same:
Original: x^2 + 2x + 7
Step C: x^2 + 2x + 8
So, Jennifer actually needs to subtract 1 from the 7 if she wants to add 1 into the parenthetical expression:
Correct Step C: (x^2 + 2x + 1) + 7 - 1 = (x^2 + 2x + 1) + 6
Now, the correct vertex form is: (x + 1)^2 + 6
Hope this helps!
Answer:
Concept: Mathematical Analysis
- They go in opposite directions
- They start at the same point, let's define that as (0,0) on the ordinary differntiable x-y axis
- Hence Tom can ride 20 units left in one hour and Juanita can ride 20 units right in one hour.
- We want to know the distance they are at the end of 2 hours
- So we set up the equation y= 20(x)
- Let x be the hours and y be the distance
- So 20×2=40 miles
- At the end of 2 hours they will be 40 miles apart assuming constant rate of change and a starting point of (0,0)
The lowest denominator is 5/6 and 3/4 is a greater value than 5/6
