solve the equations in parts a and b using inverse operations. check your solutions. in your final answer, include all of your work.
part a: 5 + x2 = 2x2 + 13
part b: 5 + x3 = 2x3 + 13

answer: (1,3) and (-2,0) i think.

they aren't great and cause destruction, idk man

(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.
