+16 The graph of y=f(x) is a parabola whose vertex is at (1,-2). The graph of y=f(x-3) is also a parabola. Where is the vertex of the graph of y=f(x-3)
Thank you in advance!
+410 f(x - 3) represents a translation right by 3.
Therefore, the whole graph is shifted right by 3, meaning the vertex shifts right by 3.
Shifting right by 3 means that 3 is added to the x coordinate.
Therefore the new vertex is (1 + 3, -2) = (4, -2).
Alternatively, if you don't know translations: Use vertex form:
f(x)=a(x−1)2−2 represents a parabola of vertex (1, -2), where a is a constant
f(x−3)=a((x−3)−1)2−2=a(x−4)2−2, so looking at this form, you know the vertex is (4, -2).
