{(3, 0), (– 2, – 2), (7, – 2), (– 2, 0)}

d)

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

Simply 8x squared + 5(7x squared- x) - 2x =
