Let f(x)=4x 2
+13x−3 Using the definition of derivative, f ′
(x)=lim h→0
​
h
f(x+h)−f(x)
​
, enter the expression needed to find the derivative at x=2. f ′
(x)=lim h→0
​
After evaluating this limit, we see that f ′
(x)= Finally, the equation of the tangent line to f(x), in point-slope form, where x=2 is
