Part A
We have

. To solve for the x-intercept, we set f(x) equal to 0. That is

Take the square root of both sides,
The x-intercept is (-2,0).
To solve for the y-intercept, we set x=0. That is
The y-intercept is (0, 8)
The coordinates of the optimum point are actually the vertex which can be easily seen from the vertex form equation given above. The minimum point is
(-3, -1).
Part B.
We have

.
Factor out -2

Complete the square

Simplify

Part C
We have

.
The maximum height is 12.25 feet after 0.875 seconds from the time of the jump. The dolphin will be back in the water after 1.75 seconds. The graph of the jump is shown in the photo.
Answer:
-5
Step-by-step explanation:
Answer:
12 1/12
Step-by-step explanation: so, we have to make the bottom number the same as eachother or we will not be able to add effectively. So the first number that both 4 and 6 go into is 12, as you can see if we count by the numbers to get to the answer
4,8,12
6,12
So, now that we have that part figured out we would then have to multiply the top the same amount as we multiplied the bottom. So 1/4x3 and 5/6x2
So we would multiply both the top and the bottom the same amount.
1/4x3=3/12
5/6x2=10/12
So now that we have that figured out everything else is pretty straight forward.
We would add the whole numbers with eachother and the fractions with eachother.
8+3=11
3/12+10/12=13/12
so we can see that it would equal, 11 and 13/12 or 12 and 1/12
