235-4 Analyzing Graphs of Polynomial Functions
The correct choice is B.
2
56. Which polynomial represents (4x
+ 5x – 3)(2x – 7)?
3
2
F 8x
– 18x
– 41x – 21
3
2
G 8x
+ 18x
+ 29x – 21
3
2
H 8x
– 18x
– 41x + 21
3
2
J 8x
– 29x + 21
+ 18x
SOLUTION:
The correct choice is H.
For each graph,
a. describe the end behavior,
b. determine whether it represents an odd-degree or an even-degree function, and
c. state the number of real zeros.
58.
SOLUTION:
a .
b. Since the end behavior is in the same direction, it is an even-degree function.
c . The graph intersects the x-axis at two points, so there are two real zeros.
60.
SOLUTION:
a .
b. Since the end behavior is in the same direction,
it is an even-degree function.
c. The graph intersects the x-axis at four points, so there are four real zeros.
Simplify.
