Answer:
Step-by-step explanation:
You have 3 points and need to find ax2 + bx + c = y. First use (0,2). x is zero, so y = 2 = c. You have c. Now put (-1,0) into the equation. 0 = 1a -b + 2. Rearrange so you get b = a + 2. Now use the other point. a*(-2 squared) + b*(-2) + 2 = 0. Simplify and substitute (a + 2) for b and you will have the answer.

Answer:
(4, 0 )
Step-by-step explanation:
A translation of 1 unit left, subtract 1 from the original x- coordinate
A translation of 2 units down, subtract 2 from the original y- coordinate
The rule is (x, y ) → (x - 1, y - 2 ), thus
(5, 2 ) → (5 - 1, 2 - 2 ) → (4, 0 )
Just matter of combining like terms
6x - 7 - 11x + x =
(6x + x - 11x) - 7 =
(7x - 11x) - 7 =
- 4x - 7 <===
