2. Show that R is a semigroup under the operation x* y = |x|y. Does it have a left or right identity element? For each
∈R , find all elements commuting with x.​

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
