b) Determine the equation of the line tangent to the graph of f at (a,f(a)) for the given value of

f(x) = 4x2+2x, a =1

F’(a) =

y =

2.

For the function find f’ using the definition f’(x) = lim(h→0)

Determine the equation of the line tangent to the graph of f at (a,f(a)) for the given value of

F(x) = √x+2, a=2

f’(x) =

y =
