Answer:
Step-by-step explanation:
If x is -1, then the point on the parabol is (-1,4)
If x is 0, then the point on the parabol is (0,-2)
If x is 1, then the point on the parabol is (1,-6)

=-9
Answer:
C) The parabola is narrower and reflected across the x-axis.
Step-by-step explanation:
The original parabola has equation:

The transformed parabola has equation

How wide the graph is can be determined by the absolute value of the coefficient.
The smaller the absolute value of the coefficient, the wider the graph.
Since

The original graph is wider than the transformed graph.
Also the negative factor tells us there is a reflection in the x-axis.
Answer:
d
Step-by-step explanation:
7x + 2 and 10x - 9 are same- side interior angles and sum to 180° , that is
7x + 2 + 10x - 9 = 180
17x - 7 = 180 ( add 7 to both sides )
17x = 187 ( divide both sides by 17 )
x = 11 → d
