What is the orientation of =22+4β30
y=2x^2+4xβ30? That is, does it open upward or open downward? How could you change the equation to make the graph open the opposite way?
What is the stretch factor of =22+4β30
y=2x^2+4xβ30? Justify your answer.
Can you identify the vertex of =22+4β30
y=2x^2+4xβ30
by looking at the equation? If not, talk with your team about strategies you could use to find the vertex without using a table or graphing calculator and then apply your new strategy to the problem. If your team is stuck consider doing parts (i) through (iii) below.
What are the
x
-intercepts of the parabola?
Where is the vertex located in relation to the
x
-intercepts? Can you use this relationship to find the
x
coordinate of the vertex?
Use the
x
-coordinate of the vertex to find its
y
-coordinate.
Make a quick sketch of =22+4β30
y=2x^2+4xβ30
and write its equation in graphing form.

Lian is deciding which of two gyms to join. each gym charges a monthly rate plus a one-time membership fee. lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. in her work, she substituted an expression for one variable and solved for the other. this resulted in the equation 75 = 75. what can lian conclude? one gym charges $75 per month. each gym charges $75 per month both gyms charge the same monthly rate and the same membership fee. both gyms charge the same monthly rate, but not the same membership fee.
