graph of the polynomial function

I need help in passing my MA105 week 5 work assignment.

 

 

Select the correct description of right-hand and left-hand behavior of the graph of the
polynomial function.
Æ’(x) = 4x2 - 5x + 4
Falls to the left, rises to the right.
Falls to the left, falls to the right.
Rises to the left, rises to the right.
Rises to the left, falls to the right.
Falls to the left.
QUESTION 2 Describe the right-hand and the left-hand behavior of the graph of
t(x) = 4x5 - 7x3 - 13
Because the degree is odd and the leading coefficient is positive, the graph falls to
the left and rises to the right.
Because the degree is odd and the leading coefficient is positive, the graph rises to
the left and rises to the right.
Because the degree is odd and the leading coefficient is positive, the graph falls to
the left and falls to the right.
Because the degree is odd and the leading coefficient is positive, the graph rises to
the left and falls to the right.
Because the degree is even and the leading coefficient is positive, the graph rises
to the left and rises to the right.
QUESTION 3 Select the correct description of right-hand and left-hand behavior of the graph of the
polynomial function.
Æ’(x) = 3 - 5x + 3x2 - 5x3
Falls to the left, rises to the right.
Falls to the left, falls to the right.
Rises to the left, rises to the right. Rises to the left, falls to the right.
Falls to the left.
QUESTION 4 Select from the following which is the polynomial function that has the given zeroes.
2,-6
f(x) = x2 - 4x + 12
f(x) = x2 + 4x + 12
f(x) = -x2 -4x - 12
f(x) = -x2 + 4x - 12
f(x) = x2 + 4x - 12
QUESTION 5 Select from the following which is the polynomial function that has the given zeroes.
0,-2,-4
f(x) = -x3 + 6x2 + 8x
f(x) = x3 - 6x2 + 8x
f(x) = x3 + 6x2 + 8x
f(x) = x3 - 6x2 - 8x
f(x) = x3 + 6x2 - 8x
QUESTION 6 Sketch the graph of the function by finding the zeroes of the polynomial.
f(x) = 2x3 - 10x2 + 12x
0,2,3 0,2,-3 0,-2,3 0,2,3 0,-2,-3 QUESTION 7 Select the graph of the function and determine the zeroes of the polynomial.
f(x) = x2(x-6)
0,6,-6 0,6 0,-6 0,6 0,-6 QUESTION 8 Use the Remainder Theorem and Synthetic Division to find the function value.
g(x) = 3x6 + 3x4 - 3x2 + 6, g(0)
6
3
-3

7 QUESTION 9 Use the Remainder Theorem and Synthetic Division to find the function value.
f(x) = 3x3 - 7x + 3, f(5)
-343
343
345
340
344
QUESTION 10 Use the Remainder Theorem and Synthetic Division to find the function value.
h(x) = x3 - 4x2 - 9x + 7, h(4)
-28
-27
-31
-25
-29
QUESTION 11 Use synthetic division to divide:
(3x3 - 24x2 + 45x - 54) ÷ (x-6)
6x2 - 3x - 9, x ≠ 6
6x2 -3x - 9, x ≠ 6
3x2 - 6x + 9, x ≠ 6
3x2 - 6x - 9, x ≠ 6
3x2 + 6x + 9, x ≠ 6
QUESTION 12 Use synthetic division to divide:
(x3 - 27x + 54) ÷ (x - 3) x2 + 3x - 18, x ≠ 3
x2 - 3x - 27, x ≠ 3
x2 + 9x + 18, x ≠ 3
x2 + 9x - 6, x ≠ 3
x2 + 6x + 9, x ≠ 3
QUESTION 13 Use synthetic division to divide:
(4x3 - 9x + 16x2 - 36) ÷ (x + 4)
4x2 - 9, x ≠ -4
4x2 + 9, x ≠ -4
-4x2 - 9, x ≠ -4
4x3 - 9, x ≠ -4
4x3 + 9, x ≠ -4
QUESTION 14 Use synthetic division to divide: 5x2 + 45x + 25, x ≠ 1/5
16x2 + 80x + 20, x ≠ 1/5
100x2 + 45x + 400, x ≠ 1/5
20x2 + 180x + 400, x ≠ 1/5
4x2 + 21x + 20, x ≠ 1/5
QUESTION 15 Find all of the zeroes of the function.
(x - 3)(x + 9)3
-3,9
3,9
-3,-9
-3,3,9
3,-9 QUESTION 16 Find all the rational zeroes of the function.
x3 - 12x2 + 41x - 42
-2, -3, -7
2, 3, 7
2, -3, 7
-2, 3, 7
-2, 3, -7
QUESTION 17 Determine all real zeroes of f.
f(x) = x3 + x2 - 25x - 25
-5,1,0
5,0,-5
-5,-1,5
-5,0,0
5,-1,0
QUESTION 18 The height, h(x), of a punted rugby ball is given by
where x is the horizontal distance in feet from the point where the ball is punted. How
far, horizontally, is the ball from the kicker when it is at its highest point?
28 feet
13 feet
18 feet
23 feet 16 feet
QUESTION 19 The profit P (in hundreds of dollars) that a company makes depends on the amount x (in
hundreds of dollars) the company spends on advertising according to the model.
P(x) = 230 + 40x - 0.5x2
