Answer:
There is only one point in the solution set :
x = -3
Step-by-step explanation:
Notice that the function is a quadratic whose graph is represented by a parabola, When you are asked for the solution to the equation:
[tex]x^2+6x+9=0[/tex]
you are being asked about which values of the variable "x" render y = 0.
Notice as well, that the vertex of the parabola, is touching the x-axis. and recall that point on the x axis are those with y-value = 0.
Therefore, there is only one x-value for which this function will render zero. That value is x = -3.
