Question

Draw the graph of quadratic equation y2=x2-3x-4​

Answer 1

Answer:

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

x

0,1,-1,4

y

-4,-6,0,0

Answer 2

Step-by-step explanation:

put x=0

y2=(0)2-3*0-4

y2=-4

y=√-4

y=+-2

put x=-1

y2= (-1) 2-3*-1-4

y2=4-4

y=0
