Consider the diagram below. GA and FA are radii and DG and FD are tangent to circle A. Determine the value of x.

102

Step-by-step explanation:

180-36=144

x+42=144

x=102

Ok so domain is all allowed numbers look at deonomenator and don't allow any numbers that will make it zero none that means domain=all real numbers vertex in form y=a(x-h)^2+k (h,k)=vertex we have y=-2(x+3)^2-1 h=-3 k=-1 vertex=(-3,-1) range the vertex opens down so max is y=-1 y≤-1 domain is all real vertex is (-3,-1) y≤-1 C
