FAN AND MEDAL

4. Graph the function: y = x^2 -9. Identify and explain the key features of your graph. Explain how to find them algebraically.

5. Using your graph from question 4, explain whether the average rate of change is increasing or decreasing, from left to right. Justify your observations by comparing the slopes calculated between at least three different pairs of points.

@dan815 When you're done please help me!

dan815 · Answer

do u know how y=x^2 graph looks

vera_ewing · Answer

Yes, I just need help explainng the key features of the graph and explaining how to find them algebraically

dan815 · Answer

y=2x^2
is similiar to 
y=x^2 but its 2 times more compressed horizontally as y is increasing twice as much

dan815 · Answer

u can see this is true
by dividing both of them suppose
y1=2x^2
y2=x^2
y1/y2=2
