We have the following functions:
f (x) = -3x ^ 4 - 14
g (x) = -x ^ 3 + 2f
Deriving both functions we have:
f '(x) = -12x ^ 3
g '(x) = -3x ^ 2
We equal zero and clear x:
f '(x) = -12x ^ 3 = 0 ----> x = 0
g '(x) = -3x ^ 2 = 0 -----> x = 0
Substituting x = 0 in the given equations:
f (0) = -3 (0) ^ 4 - 14 = -14
g (0) = - (0) ^ 3 + 2 = 2
Answer:
the largest maximum y-value is:
B.g (x)
Answer:
The slope of graph is 
Option C is correct option.
Step-by-step explanation:
We need to find the slope (rate of change) of the graph
The formula to calculate slope is: 
Taking two points from the graph: (You can take any two points from the graph)
Point 1 (-4,-3)
Point 2 (-2,0)
We have: 
Putting values in the formula and finding slope

So, the slope of graph is 
Option C is correct option.
The correct answer would be: 18+18i
For the second work sheet:
5 2/8 - 4 1/4= 1 so NO
8 3/4 - 7 1/2= 1 1/4 so YES
2 1/8 - 1 7/8= 1/4 so NO
9 5/12 - 8 1/6= 1 1/4 so YES
Sorry if its not enough explanation, hope it helps!
