-The force in newtons needed to stretch a certain spring $x$ centimeters from its resting position is given by the polynomial function $f ( x ) = 6 x ^ { 2 }$, where 6 is the spring constant. If a force of 150 newtons is applied, how far will the spring be stretched?
A) $5 \mathrm {~cm}$
B) $25 \mathrm {~cm}$
C) $30 \mathrm {~cm}$
D) $6 \mathrm {~cm}$

To find the distance the spring is stretched, set $f(x) = 150$ and solve for $x$: $150 = 6x^2$. Dividing both sides by 6 gives $x^2 = 25$, and taking the square root gives $x = 5$ cm.
