Find the minimum value of the objective function f(x, y) = x + ysubject to the constraint y = r +1(a) Use the constraint to

Find the minimum value of the objective function f(x, y) = x² + y²subject to the constraint y = r +1(a) Use the constraint to rewrite the objective function with only a single variable. Then usesingle-variable calculus techniques to find the absolute minimum of the new function.
