Answer:
(0,6).
Step-by-step explanation:
Consider the standardised form of y=ax2+bx+c. Written as y=a(x2+bax)+c. xvertex=(−12)×ba → (−12)×0−1=0.

Answer:
A
Step-by-step explanation:
We are given the function:

And we want to find:

So, we need to determine whether or not the limit exists. In other words, we will find the two one-sided limits.
Left-Hand Limit:

Since we are approaching from the left, we will use the first equation:

By direct substitution:

Right-Hand Limit:

Since we are approaching from the right, we will use the second equation:

Direct substitution:

So, we can see that:

Since both the left- and right-hand limits exist and equal the same thing, we can conclude that:

Our answer is A.
Answer:

Step-by-step explanation:
<u>Directly Proportion</u>
It's said that y varies directly proportional as x, if:

Where k is a constant of proportionality.
We know that y=7 when x=1/2.
Using the above condition, we can find the value of k:

Solving for k:
k=14
Thus, the equation is:

The answer for rounding 19.25 to the nearest ones place is 19.
