If a kicker misses a field goal but still manages to get it into or out of the endzone, is it a touchback or does the other team get the ball from where the kick was made?

Rule 6-3-1 It is a touchback if any free kick or scrimmage kick:
a. Which is not a scoring attempt or which is a grounded 3-point field goal attempt, breaks the plane of R's goal line, unless R chooses a spot of first touching by K.
b. Whcih is a 3-point field goal attempt, in flight touches a K player in R's end zone, or after breaking the plane of R's goal line is unsuccesful.

Touchback for R, 1st and 10 at R's 20

depends on the rule code (ncaa vs nf), I'll assume NF and that answer was provided texoma_lj
