and there is F function?

sparrow2 · Answer

to find the result you need f function

sweetburger · Answer

remember this equation? $$m= (y2-y1)/(m2- m1)$$ well it can be rewriten as y is the same as saying f(x) so$$m = (f(x2) - f(x1))/(x2-x1) $$

sweetburger · Answer

oh i wrote the first equation wrong *Facepalm*

sweetburger · Answer

it should be $$m = (y2-y1)/(x2-x1)$$

mathmale · Answer

This problem, as posted, is completely solvable.  Your job is to explain the MEANING of the  expression given in the illustration.

sparrow2 · Answer

in the question written FIND @mathmale

mathmale · Answer

To "find" a numerical value for the given expression, we'd have to have a table of input and output values.  Was such a table given with this question?

sparrow2 · Answer

thats why the question isn't complete, i said that we needed f function ..@mathmale
