<span>If you are adding a constant, then the graph is either raised or lowered k units.
For example.... If you have the graph of y = x^2
and now you add 3, so your new graph of x^2 + 3, will be the same graph as x^2 but raised vertically 3 units.
The graph of x^2 - 7 will be the graph of x^2 lowered vertically 7 units.
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
Answer:
Step-by-step explanation:
steps are below
step 1
(2x+1)^2 - (x+3)^2 equation
step 2
4x^2+4x+1+(-x^2)+(-6x)+(-9) distribute
step 3
4x^2+4x+1+(-x^2)+(-6x)+(-9)
(4x^2+-x^2)+(4x+(-6x)+(1+(-9) combine the like terms
3x^2-2x-8
The answer is Create a circle from a given center with a compass.
