Step-by-step explanation:
Answer:
a. -2x^2 + 3x+5=y
b.-x^2 +5x-4=y
c.-x^2 +6x-12=y
Step-by-step explanation:
a.y=-2x^2 +bx+c
the points P and Q lie on curve
=> b=3, c=5
b. delta = b^2 +4c
x1= =4
=> =8
x2==1
=>2=b+
suppose : = a
=>
=> a=-3
b=5
a=-3 => =-3 => b^2 +4c =9 =>5^2 +4c=9 => c=-4.
c.vertex (3;-3)
=3 => b =6
= =-3 =>-b^2+4ac=12 => c=-12.
