Question

A curve has the equation y=f(x). write an expression for the slope of the secant line through the points P(3,f(3)) and Q(x,f(x)).

Answer 1

a/
slope m = [f(x)-f(3)]/(x-3)

b/
tangent y - f(3) = [lim m ,as x-->3](x-3)

Answer 2

well when you work it out i dont understand what your get will it just be f(x) - 2/(x-3)

Answer 3

ok this is your answer

Answer 4

so that is your slope..well that was easy

Answer 5

yea
