y = x² - 7x
y' = 2x - 7
Ответ: y' = 2x - 7
y = √x - 9x²
y = x^(1/2) - 9x²
y' = (1/2)x^(-1/2) - 18x
y' = 1/(2√x) - 18x
Ответ: y' = 1/(2√x) - 18x
y = 1/x + 4x
y = x^(-1) + 4x
y' = -x^(-2) + 4
y' = -1/x² + 4
Ответ: y' = -1/x² + 4
y = -2√x - 1/x
y = -2x^(1/2) - x^(-1)
y' = -2 * (1/2)x^(-1/2) + x^(-2)
y' = -1/√x + 1/x²
Ответ: y' = -1/√x + 1/x²
