Question

if f(2)=3 and f'(2)=5 find and equation of the tangent line and the normal line to the graph of y=f(x)

Answer 1

Okay, so basically, all we need to do is use y = mx + b. We're given f'(2) = 5 which means the derivative(slope) of f(x) = 5. Therefore, all we have to do is find the equation of the line by inserting the given values:

Answer 2

does x=2 ?
