Move the horizontal and vertical sliders to stretch the image of the triangle. When you've settled on a pair of transformed imag
es, record the coordinates of the images in the table. Be sure to list coordinates in both the horizontal (x) and vertical (y) directions. Also record the scale factors, nx and ny. Do this at least three times to fill the table.
ANSWER:This answer assumes that nx and ny belong to the set {0.5, 1, 1.5}.
nx A A′ B B′ C C′
0.5 (2, 1) (1, 1) (4, 2) (2, 2) (5, 1) (2.5, 1)
1 (2, 1) (2, 1) (4, 2) (4, 2) (5, 1) (5, 1)
1.5 (2, 1) (3, 1) (4, 2) (6, 2) (5, 1) (7.5, 1)
ny A A′ B B′ C C′
0.5 (2, 1) (2, 0.5) (4, 2) (4, 1) (5, 1) (5, 0.5)
1 (2, 1) (2, 1) (4, 2) (4, 2) (5, 1) (5, 1)
1.5 (2, 1) (2, 1.5) (4, 2) (4, 3) (5, 1) (5, 1.5)

Answer: x-intercepts are ( 2.775,0) and (5.225,0)
And y-intercept is (0,-29)
Step-by-step explanation:
Here the given equation is,
For x-intercept, y = 0,
Put y = 0 in the above equation of parabola,
We get,
By solving this equation,
We get, x = 2.775 or x = 5.225
Therefore, x-intercept of the given parabola are (2.775, 0) and (5.225,0)
Now, for y-intercept, x = 0
By putting x = 0 in the given equation of parabola,
We get, y = -29
Thus, y-intercept of the given parabola = (0,-29)
