Math 110 Course Resources - Derivatives Course Packet on computing derivatives using the limit definition Let f( x) = Vx. (a) Simplify (15 + h) - F(15) h Algebraically simplify your answer until you have cancelled out the factor of h in the denominator. V15 +h + V 15 (b) Evaluate lim f(15 + h) - f(15) h -0 h If an answer does not exist, enter DNE. X (c) Determine the equation of the line tangent to y = f(x) at x = 15. X Submit
