Question

Write a rule for the composition of a

reflection in the x-axis following a translation
of 7 units to the left and 3 units up.
(r-aris T₁3)(x, y) = (x-7,-y+3)
A.
B.
C.
D.
(rx-axis ° T-7,3)(x, y) = (x-7,-y-3)
(T-7.3°r-axis)(x, y) = (x-7, y + 3)
or
(T-73 °F-ais) (x, y) = (x-7,y-3)
or
1

Answer 1

(x-7,-y+3)

Explanation:

P(x,y)

-> reflection in x-axis P'(x,-y)

-> translation(-7,+3) P''(x-7,-y+3)
