Question

If y = -| the value of polynomial 2y?​

Answer 1

Step-by-step explanation:

Let f(y)=ay

2

+2y−6

Given, when y=−3,f(−3)=15

Thus,

a(−3)

2

+2(−3)−6=15

=>9a−6−6=15

=>9a=15+6+6

=>9a=27

=>a=

9

27

=>a=3

Answer 2

Answer:

2y=-2

Step-by-step explanation:

since Y=-1

2y

=2x-1

=-2
