QUESTION:

Define a relation R from R to R as follows: For all \((x, y) \in \mathbf{R} \times \mathbf{R}\),

                                             \((x, y) \in R\) means that \(y=x^{2}\).

a. Is \((2,4) \in R\)? Is \((4,2) \in R\)? Is (−3) R 9? Is 9 R (−3)?

b. Draw the graph of R in the Cartesian plane.

(x, y) in R times R

(x, y) in R

y=x^2

(2,4) in R

(4,2) in R
