Given: f(x) = 2+ sqrt(-3x+1), q(x) = (5x)/(x+2), and m(x) = abs(7 - x^2) + x, how do you find q(-2)?

Are you sure this question is correct q(-2) is undefined

Explanation:

color(green)(q(color(red)(x))=(5color(red)(x))/(color(red)(x)+2) =>q(color(red)(-2)) =(5(color(red)(-2)))/(color(red)(-2)+2)

But this has a denominator of 0 so is 'undefined' (not allowed).
