Method A: lim(h->0)(f(x+h)-f(x))/h Method B:lim(x->c)(f(x)-f(c))/x-c

Question

A) f(x)=2+5x-2x^2 at x=2

Find the slope of the tangent line to the curve at the indicated point. Find the slope using both methods.

B) Write the equation of the tangent line at x=2.

Answer 1

This is the same question as the one submitted twice previously.

You should be able to use the previous answer to solve this one!

The slope is 5-4x...and you should be able to get it by both methods!
