Math Problem Statement
-
Tentukan persamaan bayangan dari fungsi linier y = 4/3 * x + 8 yang dicerminkan terhadap sumbu x
-
Tentukan persamaan bayangan dari fungsi y = x ^ 2 + 4x - 12 oleh pencerminan terhadap sumbu x. Jika hasil bayangan (peta) dari fungsi tersebut adalah g(x) maka nilai g(- 2)
-
Diketahui lingkaran dengan persamaan (x - 2) ^ 2 + (y - 3) ^ 2 = 4 dicerminkan terhadap sumbu y. Tentukan bayangannya.
-
Diketahui fungsi y = 5x + 2. Tentukan bayangan apabila dicerminkan terhadap sumbu x selanjutnya hasil bayangan dicerminkan terhadap sumbu y.
