The rule (x, y ) → (x + 4, y - 6 )
means add 4 to the original x- coordinate and subtract 6 from the original y- coordinate, thus
P(- 8, 3 ) → P'(- 8 + 4, 3 - 6 ) → P'(- 4, - 3 )
Q(- 8, 6 ) → Q'(- 8 + 4, 6 - 6 ) → Q'(- 4, 0 )
R(- 3, 6 ) → R'(- 3 + 4, 6 - 6 ) → R'(1, 0 )

a.
a= y-k/ (x-h)^2
-12e-x + 8 = 7
-12e-x = 7-8
-12e-x = -1
12e-x = 1
e-x = 1/12
ln(e-x) = ln(1/12)
x = -ln(1/12)
x = -2.485
