Question

draw the graph of y=x²-3x-4​

Answer 1

Answer:

Solution:

If x = 0,

⇒  y= 02  -  3(0) -  4 = - 4

If x = 1

⇒ y= 12 -  3(1) -  4 = - 4 = 1 - 3 - 4 = - 6

If x = -1  

⇒ y = y= (-1)2  -  3(-1) -  4 = 1+3 - 4 = 0

If x = 4

⇒  y = ​​​​​​​(-1)2   -  3(4) -  4 = 16 - 12 - 4 = 0

The coordinate points of the given equation are
