Answer:
The correct answer is A. -1
Step-by-step explanation:
The y-intercept is simply the name of the point where the line passes through the y-axis. Since you already stated that that point comes at -1, we know the intercept is -1.

The box plot tells us about the lower limit, first quartile, median, third quartile, and upper limit.
Step-by-step explanation:
Box plot:
It displays the five-number summary of a set of data. The five-number summary is the lower limit, first quartile, median, third quartile, and upper limit. We draw a box in a box plot from the first quartile to the third quartile. A vertical line goes through the box which represents the median. Anything that lies beyond the upper limit or the lower limit is know as an outlier.
From the information given, we can say that:
The left-most point on the plot is 20 and the right-most point is 95 which means 20 and 95 are the lower and upper limit respectively.The box is labeled 35 on the left edge and 60 on the right edge which means 35 is the first quartile and 60 is the the third quartile. A vertical line is drawn inside the rectangle at the point 55 which means 55 is the median of given data.We cannot know about the mean of data with the given information

Step-by-step explanation:
You have done the hard part: finding the vertex.
__
The leading coefficient is the coefficient of the x^2 term. It is +1, a positive number, so the parabola <em>opens upward</em>.
__
The x-coordinate of the vertex for a parabola described by ...
f(x) = ax² +bx +c
is ...
x = -b/(2a)
For this parabola, a=1, b=6, c=2, and the x-coordinate of the vertex is ...
x = -6/(2(1)) = -3
The value of the function at that point is ...
f(-3) = (-3)² +6(-3) +2 = 9 -18 +2 = -7
The coordinates of the vertex are ...
(-3, -7)
__
The axis of symmetry is the vertical line through the vertex. Its equation will be ...
x = -3
__
Some points on the graph can be found by choosing x-values near the vertex value. They will be symmetrical about the axis of symmetry. When the leading coefficient is 1, the y-values will increase above the vertex point by the square of the x-distance from the vertex. The point at x= (-3 +2) will be at y = (-7 +(2²)), or (x, y) = (-1, -3). The symmetrical point is (-5, -3).
