For Domain<span>, you just need to watch out for Square Roots and/or Fractions! 1) a POLYNOMIAL (no square roots or fractions), i.e. f(x) = x^2 + 3x + 1, </span>domain<span> is "all real numbers." 2) a FRACTION (w/ no square root), i.e. f(x) = (2x+1)/(x^2+5x+6). Set bottom "not equal" to zero.</span>
Step-by-step explanation:
z = b - ma
z - b = ma
z - b / m = a
The answer is C
Because all you need to do is divid by either 3 or 12
