Expert Solution
Step 1

We have given  a function 

y =3 sinx2 

so find x were graph across x-axis 

now we consider the value of y=f(x) 

                                                at y=0    gives the value of x=0 , 2π , 4π 

                                                     y=3  gives the value of x=π and 

                                                      y=-3 gives the value of x=3π

                                                      so we finally got the answer is option b is correct at y=3 icross  the value of x=π
