If 3K 1 M, which statement is true? O A. Tk and [M meet at a 45° angle.
O B. TK and I are coplanar and do not intersect.
O C. TK and Im are not in the same plane.
D. TK and IM meet at a 90° angle.

middle maybe?

step-by-step explanation:

(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.

i believe the answer is the top one, correct me if im wrong.
