Answer:
C & D
Step-by-step explanation:
x² + 3x - 3 = 0
a = co efficient of x² = 1
b= co efficient of x = 3
c = constant = -3
roots = (-b ± )/2a
= (-3± )/2*1
= (-3±)/2
= (-3±√21)/2
Is 3x^2 − y = 5 a function or not a function

To find:
The equation that connects y with x.
Solution:
It is given that, y is directly proportional to x. So,
...(i)
Where, k is the constant of proportionality.
We have, when
. Substituting these values in (i), we get
Divide both sides by 5.
Substituting in (i), we get
Therefore, the required equation is .
