#y=x^2+4x-12#
Explanation:
It is a parabola.
Its x-intercepts are
Equation can be formed like this -
#x=-6#
#x+6=0#
#(x+6)# is one of the factors of quadratic equation.
#x=2#
#x-2=0#
#x-2=0# is another factor of quadratic equation.
The quadratic function is -
#y=(x+6)(x-2)#
#y=x^2+6x-2x-12#
#y=x^2+4x-12#
