Answer:
Linear function
Step-by-step explanation:
x y Ist difference
-6 -27 -
-5 -21 -21 - (-27) = 6
-4 -15 -15 - (-21) = 6
-3 -9 -9 - (-15) = 6
-2 -3 -3 - (-9) = 6
Since, Ist difference is common in the given table,
(Common difference = 6)
It's a linear function.

Step-by-step explanation:
Answer:
Step-by-step explanation:
2x + 3y - x - 9
x + 3y - 9
Answer:
Step-by-step explanation:
y=a(x-0)(x-2)
=a(x^2-2x)
=a(x^2-2x+1-1)
or y=a(x-1)^2-a
(1,5) lies on it.
5=a(1-1)^2-a
5=0-a
or a=-5
so y=-5(x-1)^2+5
