B, E and F.
The transformation f(x) > f(x + a) moves f(x) a units to the left.
So when there is an increase in the number added to x in the parentheses the graph moves to the left.
So B is one because of the (x - 1)2 ---> (x + 1)2
The others are E and F.
in vertex form
the vertex is (h,k) and the axis of symmetry is x=h
put into vertex form
the vertex is (0,c)
the axis of symmetry is x=0
State the vertex and axis of symmetry of the graph of y=ax^2+c
General form of quadratic equation is
There is no bx in our given equation, so we put 0x
Given equation can be written as
a=a , b=0
Now we use formula to find vertex
Now we plug in 0 for 'a' and find out y
So our vertex is (0,c)
The axis of symmetry at x coordinate of vertex
So x=0 is our axis of symmetry
1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
i am only able to answer the first part. i am not sure about the second part. sorry
i think the answer is a p = 78
there are 6 sides of a hexagon, multiply 13 x 6
