do you have to use the limit definition to find the derivative?

anyway, find the derivative and plug in x = 2, that will give you the slope of the tangent line (note that the slope of the normal line is the negative reciprocal of this slope).

when done, find the point on the graph where x = 2. (plug in x = 2 into the original equation and solve for y). call this point

then use the point slope form to find the equation of the tangent line:

where is the slope.

do one line for the tangent and another for the normal line
