# FNGR 2 | Lesson 4 | Explore (Graphing Quadratics, Again)

Either by hand, with a graphing calculator, Desmos or Geogebra graph the following functions:

a) $$f(x) = x^2$$

b) $$f(x) = (x+2)^2$$

c) $$f(x) = (x-3)^2$$

d) $$f(x) = (x-5)^2$$

Describe in your own words what you notice about the graphs of the functions.

What happens when you evaluate $$f(x) = (x-3)^2$$ at $$x=3$$, what is the significance of that point?
