Calculate the integral of f(x, y)=7xf(x, y)=7x over the region d bounded above by y=x(2−x)y=x(2−x) and below by x=y(2−y)x=y(2−y). hint: apply the quadratic formula to the lower boundary curve to solve for yy as a function of x

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

where is the questions

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
