$limf\left(x\right)=-1$
$x\to 2$

$limf\left(x\right)=-1$ Given $x\to 2$
$lima{x}^{2}-8x=-1$ Substitute $f\left(x\right)=a{x}^{2}-8x$ $x\to 2$
$a{2}^{2}-8\left(2\right)=-1$ Evaluate the limit by substituting x=2.
$4a-16=-1$ Simplify.
$4a=15$ Add 16 on both sides.
$a=\frac{15}{4}$ Divide both sides by 4.
