A. (-5,6).(-5, 4), (2, 6), (2, 4)
B.(6,-5).(-4,5), (6,2).(-4.2)
C. (5.-6). (5, 4).(-2,-6).(-2,4)
D.(-6.5),(4.5),(-6.-2).(4.-2)

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
