Step 1 :Choose two values for \(x\), let's choose \(x=1\) and \(x=16\).
Step 2 :Calculate the corresponding \(t(x)\) values for each \(x\).
Step 3 :For \(x=1\), calculate \(t(1)=-\frac{3 \sqrt[4]{1}}{10}=-\frac{3}{10}=-0.3\). So, the point is \((1, -0.3)\).
Step 4 :For \(x=16\), calculate \(t(16)=-\frac{3 \sqrt[4]{16}}{10}=-\frac{3 \cdot 2}{10}=-0.6\). So, the point is \((16, -0.6)\).
Step 5 :\(\boxed{\text{Therefore, two points on the graph of this function that fit within the given [-10,10] by [-10,10] grid are (1, -0.3) and (16, -0.6).}}\)
