Determine the direction, form, strength, and any outliers on the scatterplot. Scatterplot with x-axis labeled year and y-axis labeled megawatts. The 18 points plotted are 1982 and 76.2, 1983 and 50.6, 1984 and 46.4, 1985 and 35.5, 1986 and 31.1, 1987 and 26.1, 1988 and 21, 1989 and 15.6, 1990 and 14.9, 1991 and 13.8, 1992 and 13, 1993 and 13, 1994 and 10, 1995 and 10, 1996 and 7, 1997 and 6.9, 1998 and 6.6, and 1999 and 6. This scatterplot has a negative association, form is slightly curved, strength is weak, and there are no apparent outliers. This scatterplot has a positive association, form is linear, strength is strong, and there is one possible outlier. This scatterplot has a negative association, form is slightly curved, strength is strong, and there is one possible outlier. This scatterplot has a positive association, form is slightly curved, strength is weak, and there are no apparent outliers. This scatterplot has a negative association, form is linear, strength is weak, and there is one possible outlier.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

a.)the line for function b is steeper

17,000 is the correct answer.

(2,0) and (-3,0)
