6. Use the limit formula below to find the slope of the tangent to the function f (x ) = 2 @x=5 . You may not use any other method to find the slope of x+3 the tangent. [4] TangentSlope or IROC = lim f(ath) - f(a) h ax=a h -0 7. Find the derivative, f'(x), of the function f(x) =2x2 -x +3 by applying the following limit formula. You may not use any other method to find the derivative function. [5] f'(x) = lim f(xth) - f(x) h h-0
