Three vertices of parallelogram PQRS are P(-3, 2), Q(2, 6), and R(3, 3). Find the coordinates of vertex S.​

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?

Pls brainliest will be awarded if answer is correct

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)
