(a) Asks to differentiate an equation C: 4x² - y³ - 4xy + 2^y = 0Then use the fact that point P (-2,4), lies on C to find an expression for dy/dx Differential of form 8x - ...

In order to solve this, we need to bring all of the x values to one side, we can do this by subtracting the 2x from both sides7x + 6 - 2x > 1 + 2x - 2x5x + 6 > 1 We then need to move the values onto...
