Question

Use linear approximation, i.e. the tangent line, to approximate 492 as follows: Let f(x)=x . The equation of the tangent line to f(x) at x=49 can be written in the form y=mx+b where m is? b is?

Answer 1

Think about the graph of \(f(x)=x\). What would a *linear* approximation of a *line* look like?
