Answer:
Step-by-step explanation:
Since they give us the coordinates of the minimum of the parabola (the parabola's vertex), we start by writing the function in vertex form:
Now we use the fact that the point (0,1) is on the graph of the parabola, which means that when x=0, the value of the function (y) must be equal to 1.
We apply this to the expression we found above:
which gives us: 
therefore, 
Now we write the function using the value of the constant a we just found:
and next we find the square of the binomial (x+1) to express the function in standard form:

Answer:
The area of the rectangular playroom is 260 feet² .
Step-by-step explanation:
Given:
The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.
Now, to find its area we need the length .
So, putting the formula of perimeter we get it's length:
Let the length be l .
Perimeter = 2( length + width)
subtracting both sides from 20:
Dividing both sides by 2:
Length is 26 feet.
And, to get the area we put the formula of finding the area:
Therefore, the area of the rectangular playroom is 260 feet² .
