Answer:
see explanation
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , thus
A(4, - 1 ) → A'(- 4, - 1 )
B(3, - 3 ) → B'(- 3, - 3 )
C(0, 2 ) → C'(0, 2 )
5
your answer is 5 the greatest common factor is 5
10= 5
25=5
15= 5
C
I explained in my last answer but someone deleted it
y = x² - 2x - 3
y + 4 = C(x - 1)²
To determine C, use x = 4, y = 5
5 + 4 = C(4 - 1)²
9 = 9C, C = 1
y + 4 = (x - 1)² = x² - 2x + 1
