Write a Function in Slope-Intercept Form

Key Questions

  • Assuming your function is expressed using #x# as a variable, evaluation of the function involves replacing each occurrence of #x# with some per-specified value.

    That is evaluation of a function is always "at some point#.

    For example if your function is
    #f(x) = 3x^2 -x +4#
    and you are asked to evaluate this function at #x=2#

    #f(2) = 3(2^2) -2 + 4 = 14#

    (Since this question was asked under "Functions in Slope-Intercept Form, your function might look more like:
    #y = 5x + 7#
    and you might be asked to "evaluate #y# at #2#", but the same idea applies:
    #y = 5(2) + 7 = 17# )
