Answer:
Equation of the axis of symmetry is: x = 3
Step-by-step explanation:
The equation
is the equation of a parabola, of the form
whose vertex is located at the x-coordinate:
Then, for our case the x position of the given parabola, is:
Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:
x = 3
Answer:
C
Step-by-step explanation:
We must compute the derivatives and check if the equation is satisfied.
A. . Differentiate again to get
, then
so this choice of y doesn't solve the equation.
B. and
, then
so y is not a solution
C. hence
. Then
so y is a solution.
D. and
, then
thus y isn't a solution
E. hence
. Then
then y is not a solution.
