Question

Which phrase best describes the translation from the graph y = 2(x – 15)2 + 3 to the graph of y = 2(x – 11)2 + 3?

Answer 1

Answer:

The translation is left 4 units

Step-by-step explanation:

we know that

$y=2(x-15)^{2}+3$

Is a vertical parabola open upward with vertex at (15,3)

$y=2(x-11)^{2}+3$

Is a vertical parabola open upward with vertex at (11,3)

so

The rule of the  translation of (15,3) ----> (11,3) is equal to

(x,y) ----> (x-4,y)

That means ----> The translation is left 4 units
