Step-by-step explanation:
Here is an inserted image of the graph and coordinates.
Answer:
See below description.
Step-by-step explanation:
The function
has the following characteristics:
- Factors:

- Zeros/roots: x=0, x=-1, amd x=4
- Positive leading coefficient
- Graph starts down and curves up through -1 on the x-axis and back down to cross through 0. It curves back up again through 4 and finished off heading into positive infinity.
- Its graph is the shape of a sideways S.
- It has a relative maximum at 1.128 and relative minimum value of -13.128
Answer:
P = 16x + 8
Step-by-step explanation:
Perimeter of a rectangle
= 2(L + W)
Given
L = 5x + 4 and
W = 3x
Therefore
Perimeter = 2(5x + 4 + 3x)
Rearrange the expression
P = 2(5x + 3x + 4)
P = 2(8x + 4)
Now expand the bracket
P = 2 x 8x + 2 x 4
P = 16x + 8
