Multiply: Enter your answer as a single, reduced fractionFind the values of I where the tangent line to the graph of x} = E is parallel to the line 3'; = Sx + 2 Give exact answers [not decimal approximations}. (Tip: To enter V'E, type either sqrtfaj or rpm; The greater solution is x = C] and lesser solution is x = :l Find the point where the tangent line to y = " at c = 0.2 crosses the x-axis. x-interceptSuppose that the position of a particle is given by s = f(t) = 2t" + 4t + 9.
