If f(t)= 3t^2-2, find f(k-2)

DedPeter [7]

By plugging (k-2) in t, we can write that
$f(k-2)=3(k-2)^{2}-2=3(k^{2}-4k+4)-2=3 k^{2}-12k+12-2=$ $3 k^{2}-12k+10$

What is the constant of variation, k, of the direction variation, y = kx, through (-3, 2)

Bond [772]

$\bf \qquad \qquad \textit{direct proportional variation}
\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}
\\\\[-0.35em]

(\stackrel{x}{-3},\stackrel{y}{2})\textit{ we also know that }
\begin{cases}
x=-3\\
y=2
\end{cases}\implies 2=k(-3)\implies \cfrac{2}{-3}=k$
