#### Lessons

• 1.
Reflection in the x-axis
Reflect a quadratic function in the x-axis:
a)
Sketch the following functions on the same set of coordinate axes:
$y = x^2$      VS.      $-y = x^2$

b)
Compared to the graph of $y = {x^2}$, the graph of $- y = {x^2}$ is a reflection in the _______________ .

• 2.
Compared $y = x^2$ to basic quadratic function:
i) describe every step of transformations
ii) use transformation concepts to sketch the function
a)
$y = 2(x-3)^2-8$

b)
$y=- \frac{1}{3}(x+5)^2+4$
