Find the derivative of the following using the formal definition: h(x) - -12x2 -4x+5 hex)= -12x24x +5 2. Find the slope of the tangent line to the graph of fat x = 4, given that f (x) = -x2 + 4Vx a)-8 b) -10 c) -9 d) -5 e) -7 - 42+ 4 541 3. Find the derivative y = Vx 1 VX (write final answer without negative exponents, but you do not have to combine frac 4. Find the derivative: f (x) = 12 - 3x + 1 5. Find the derivative (Hint: distribute first to rewrite the function!): y = Vx(Vx + 3) 6. Find the slope of the tangent line to f (x) = = x3 + 3x + 3 at the point (-2,-1)
