Hello everyone, in this problem we need to find the derivative of f of 5x. So, now let us take z to be 5x and y to be equal to f of 5x can be written as y to be f of z. Now, we differentiate both sides with respect to x. So, we get for z we will use chain rule. So, we get dy by dx to be equal to d by dx of f of z. So, dy by dx will be equal to d by dz of f of z into dz by dx. So, this will be dy by dx will…
