Question

Each of the function graphs represents an original function, marked by a dotted line graph, and a translated graph, marked by a solid line graph. Which graph shows that y=f(x−3)
is the result of the function y=f(x)
being translated by 3 units?(1 point)

The solid parabola starts from left parenthesis negative 8 comma 9 right parenthesis peaks down at left parenthesis negative 5 comma 0 right parenthesis ends at left parenthesis negative 2 comma 9 right parenthesis. The dotted parabola starts from left parenthesis negative 3 comma 9 right parenthesis peaks down at left parenthesis 0 comma 0 right parenthesis ends at left parenthesis 3 comma 9 right parenthesis.

Answer 1

The first graph (the parabolas). The solid parabola is the dotted parabola shifted 3 units to the right (the vertex moves from (0,0) to (3,0)), which is y = f(x−3).
