(d)
Step-by-step explanation:
Given

The intercepts
The x intercepts are where the graph crosses x axis.
From the attached plot, they are:
and 
These represent the start and end of the ball that is launched.
Hence, (d) is true
Answer:
Remember that the maximum rate of change of f at a point u is the length of the of the gradient vector evaluate in u, and the direction in which it occurs is in direction of the gradient vector evaluate in u.
The gradient vector of f is

Then, the maximum rate of change is
in the direction of (5,8).
3 * N = 1
The multiplicative inverse is just the reciprocal of the number. The reciprocal is just " flipping " the number. So the reciprocal of 3 (or 3/1) is 1/3. And any time u multiply a number by its multiplicative inverse (reciprocal), the result is 1
3 * 1/3 = 3/3 = 1.....so N is ur multiplicative inverse
