Answer:
They are different because they have different signs
Step-by-step explanation:
In 4,9 both values are positive whereas in 4,-9 the 9 is negative and the 4 is positive.
Im so sorry I don't know how to do B but I do know a and c.....
A) 1.44
C) 3
Answer:

Step-by-step explanation:
Given

Required
Fill the array using doubling and halving
Question is incomplete, as the array is not given.
However, the solution is as follows:

Double 25 and half 68

Double 50 and half 34

The above is now easy to solve

Answer:
g(x) = 7(-x)³
Step-by-step explanation:
The cubic parent function is given as; f(x) = x³
Now, we are told that it reflects across the y-axis. This means that the new function will take the form;
g(x) = f(-x)
Thus, the new function is;
g(x) = (-x)³
Now,we are told that this new function stretches by multiplying by 7. Thus, we now have;
g(x) = 7(-x)³
Answer:
The graph of the function
is attached as image below.
Analysis:
We have two intersection points in the graph
The function
intersects the y-axis at points (0,4)
The function
intersects the x-axis at points (-16,0)
f(x) is positive for x>-`16
f(x) is negative for x<-`16
