Use linear approximation, i. E. The tangent line, to approximate 2.86 as follows: Let f(x)=x6. The equation of the tangent line to f(x) at x=3 can be written in the form y=mx+b m? B?

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

table 3 represents a direct variation function. : )
