If f(x) = -3x + 12– 7, Your English teacher said that the transformations are Horizontal translation 12 units left Vertical translation 7 units down Horizontal reflection over the y axis Horizontal compression by a factor of 3 What mistake did your English teacher make? What are the correct transformations?

Respuesta :

Given the function f(x) = -3x + 12– 7,

According to the function, we can see that +12 was first added to the function -3x. This means that the horizontal translation is 12 units to the right not to the left

since -7 was further added, this means that the vertical translation is 7 units down (along the negative x axis)
