Answer:
(0,-2); The y-intercept is y=-2.
Step-by-step explanation:
Recall that the y-intercept is simply (0, y). In other words, we simply need to plug zero into the equation to acquire the y.
Thus:



In points form the answer is (-8,-4) and in equation form the answer is x=-8, y=-4

Answer is : 8v^3+ 14v^2+11v+3
For cubic feet
Solution
Formula : volume base area x height
So base area = 4v^2 +5v+3
Height = 2v+1
So multiply
Volume =(4v^2+5v+3) x(2v+ 1)
The rest is below
