Use the product rule to find the derivative of j(x) = (5x)(4x-1). If we set f(x) = 5x and g(x)= 422-1, then f'(x) == and g'(x) = Thus j'(x)= Simplifying, we have j'(x) = -(52). Find the derivative of: -42+ 6 26 Type your answer without fractional or negative exponents. Use sqrt(x) for Use the chain rule to find the derivative of 15x4(3+14z5) (3+7210) - (4x-1) + + 63x + 720 Type your answer without fractional or negative exponents. Use sqrt(x) for 3 The slope of the tangent line to the curve y = I at the point 8, 3 is: The equation of this tangent line can be written in the form y = mx + b where: m is: bis:
