Question

Write an equation for each translation of . 2.5 units left

Answer 1

     A translation to the left or right is accomplished by adding or subtracting the amount to the x term before any other operation is done. You want to move -2.5 or 2.5 to theleft which is the negativ direction. So you'd get

 

y = | x - -2.5 | or y = | x + 2.5

 

OTHER EXAMPLES

y = ( x + 2.5)^2  is a translation of y = x^2 ....2.5 to the left

y = ( x - 5)^3 is a translation of y = x^3....... 5 to the right

Answer 2

y = lx+2.5l  

Answer 3

y = |x + 2.5|
