A quadratic polynomial has x-intercepts at x = −3 and x = 4 and opens upward. Which of the following could represent the polynomial? a)
y
=
−
(
x
+
3
)
(
x
−
4
)
y = -(x + 3)(x - 4)
y
=
−
(
x
+
3
)
(
x
−
4
)
b)
y
=
(
x
−
3
)
(
x
+
4
)
y = (x - 3)(x + 4)
y
=
(
x
−
3
)
(
x
+
4
)
c)
y
=
(
x
+
3
)
(
x
−
4
)
y = (x + 3)(x - 4)
y
=
(
x
+
3
)
(
x
−
4
)
d)
y
=
(
x
+
3
)
(
x
+
4
)
y = (x + 3)(x + 4)
y
=
(
x
+
3
)
(
x
+
4
)
