Verify that the set of automorphisms of g has the following properties:
a) the composition of two automorphisms is an automorphism.
b) the identity permutation is an automorphism.
c) the inverse of an automorphism is also an automorphism.

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
