Answer:
x=4/3, y=2
x=8/3, y=10/3
x=22/3, y=24/3
Step-by-step explanation:
By following the rule given, you can insert the values you already know to find the values that you don't know!
The answer this is the 3rd option choice: Reaches a maximum height of 549 feet after 5.75 seconds.
we know that
Any function f(x) is continuous at x=a only if

We can see that this curve is smooth everywhere except at x=3
so, we will check continuity at x=3
Left limit is:

Right limit is:

Functional value:

we can see that left limit is not equal to right limit
so, limit does not not exist
so, this function is discontinuous at x=3
Since, limit does not exist
so, there will be non-removal discontinuity at x=3
so, option-C........Answer
Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
