<em>Answer:</em>
<em>1cm = 50
</em>
<em>2 cm = 50 x 2
</em>
<em>3cm = 50 x 3
</em>
<em>and the inverse:50m = 50/50 = 1cm
</em>
<em>100m = 100/50 = 2cm
</em>
<em>150m = 150/50 = 3cm
</em>
<em>381m = 381/
</em>
the answer is (f/g)(x) = 2(x^2 - 7) + 1
= 2x^2 - 14 + 1
= 2x^2 - 13
X = - 1/3 or an alternate form x = -0.3, x = -3 to the power of -1
