Answer:
A: 
Step-by-step explanation:
After graphing the equation, the highest point is (-1,-2). Since f(x) is the 2nd number in the coordinates (x, f(x)), the range is 
A. Zero points of intersection
the lines are parallel
x= 2
Step-by-step explanation:
The answer for what does x= is,
x = 2
Factor the following:
x^2 - 4 x + 3
The factors of 3 that sum to -4 are -1 and -3. So, x^2 - 4 x + 3 = (x - 1) (x - 3):
Answer: (x - 1) (x - 3)
