vertex#=(-1,17)#

Explanation:

The general equation of a quadratic equation in vertex form is:

#y=a(x-h)^2+k#

where:
#a=#vertical stretch/compression
#h=#x-coordinate of vertex
#k=#y-coordinate of vertex

Looking back at the equation, #y=-(x+1)^2+17#, we can see that:

  • #h=-1#
  • #k=17#

Keep in mind that #h# is negative and not positive even though it appears to be in the equation.

#:.#, the vertex is #(-1,17)#.
