Find the equation of the tangent line to the curve y = 8 sin a at the point (7,4). 6 The equation of this tangent line can be written in the form y=mx+b where m and b = 7 Find the derivative of f(x) = -6x - x4 Type your answer without fractional or negative exponents. Use sqrt(x) for x. f'(x) = = X x + 7 Give exact answers (not decimal approximations). Let f(x)= = Find the values of x where f'(x) = 6. The greater solution is x = The lesser solution is x =
