Question

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)`?

Answer 1

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).
