Answer:
Option 1, 2, 5 are the correct answer.
Explanation:
We have the quadratic equation,
First derivative of the equation is given by 2x - 6 = 0
So x = 3
At x = 3 the value of quadratic equation is extreme, corresponding y is given by , So extreme value is at (3,-7)
Second derivative of the quadratic equation is given by 2 ( positive value)
Second derivative is positive so graph of equation has a minimum value.
Now root of the equation is given by
or
Option 1, 2, 5 are the correct answer.
