4-7 Transformations of Quadratic Graphs
2
– 12
y = 4(x + 3)
Write each function in vertex form.
4. MULTIPLE CHOICE Which function is shown in
the graph?
1.
SOLUTION:
ANSWER:
2
A y = –(x + 3)
+ 6
2
y = (x + 3)
– 7
2
B y = –(x – 3)
– 6
2
C y = –2(x + 3)
+ 6
2.
2
D y = –2(x – 3)
– 6
SOLUTION:
SOLUTION:
From the figure, the vertex (h, k) of the parabola is
(–3, 6). Substitute (–5, 2) for (x, y) in the vertex form
to find a.
The graph represents the function
The answer is choice A.
ANSWER:
2
y = –2(x – 2)
+ 3
ANSWER:
A
3.
Graph each function.
SOLUTION:
5.
SOLUTION:
The vertex is at (3, –4) and the axis of symmetry is x
= 3. Since a = 1 > 0, the graph opens up.
ANSWER:
2
y = 4(x + 3)
– 12
4. MULTIPLE CHOICE Which function is shown in
ANSWER:
the graph?
