Question

Problem 13

Answer 1

Given information

we have two given curves which are  originally parabolas and their standard form is :  

by standard form of parabolas we can find their vertices by putting x=0 in each we have, 

 

                                                                                                              

hence vertices of  parabolas are ( 0,12) &(0,-6).

Step-by-step explanation

Step 1.

now we find the intersection points of the curves ,

for this, we put:

 

 

 

                  
now we put y=3 in , we get       

 

 

hence both the curves intersect at (-3,3) &(3,3).
