Graphing Quadratic Basics

f(x) is transformed so that it maps onto g(x). Which equation would correctly represent g(x)

• g(x)=f(x + 3)

• g(x)=f(x - 3)

• g(x)=f(x) + 3

• g(x)=f(x) - 2

Graphing the quadratic in Desmos is another way to find the vertex of a parabola.

What are the x-intercepts (solutions)?

• (-2,0) and (2,0)

• (0,-4)

• (-2,-4) and (2,-4)

Does this question have a maximum or a minimum?

• Maximum

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• none of these

What are the green points called?

• axis of symmetry

• vertex

• y-intercept

• x-intercepts

True or false: The y-intercept and vertex are the same

• True they are both at (0,-4)

• True they are both at (-2,0)

• False the y-intercept is at (-2,0)

• False the y-intercept is at (2,0)

What is the green dot on the parabola called?
