Hey, im not really sure but i think it is that 1. x=96 y=11 2. x=16 y=15 3.x=81 y=18
Then you just substitute the numbers into the letters. For example,
11-96(2)= -181
15-16(2)= -17
18-81(2)= -144
Adding two or more vectors is correct.
Answer: 4) y = -1/3x² + 2x - 1
Step-by-step explanation:
Given :
y = 
+ 2
Expanding (x-3)² will give :
- 6x + 9
substituting into the function , we have :
y = 
- 6x + 9 ) + 2
Expanding , we have
y = 
+ 2x - 3 + 2
y = 
+ 2x - 1
