Answer:
B'(- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
Answer:
D
Step-by-step explanation:
The equation of the parabola is of the form
y = ax² + c ( where c is the y- intercept )
Here c < 0
Since the parabola has a maximum value and opens down then a < 0
Thus the only equation that could represent this parabola is
y = - x² - 3 → D
