A) \[2x-y-3=0\]
B) \[2x-y+3=0\]
C) \[2x+y+3=0\]
D) None of these
Correct Answer: B
Solution :
Equation of parabola is \[{{Y}^{2}}=4X\], where \[X=x+\frac{5}{4}\] Tangent parallel to \[Y=2X+7\]is \[Y=2X+\frac{a}{m}\] Þ \[y=2\left( x+\frac{5}{4} \right)+\frac{1}{2}\]Þ\[y=2x+3\] i.e., \[2x-y+3=0\].You need to login to perform this action.
