which table shows a function that is decreasing only over the interval (-1, 1)?
Answer
# Explanation:
## Step1: Check first table
For \(x\) values from \(-2\) to \(-1\), \(f(x)\) increases from \(0\) to \(3\). From \(-1\) to \(1\), \(f(x)\) decreases from \(3\) to \(-3\). From \(1\) to \(2\), \(f(x)\) increases from \(-3\) to \(0\).
## Step2: Check second table
For \(x\) values from \(-2\) to \(-1\), \(f(x)\) decreases from \(10\) to \(8\). From \(-1\) to \(1\), \(f(x)\) decreases from \(8\) to \(-8\). From \(1\) to \(2\), \(f(x)\) decreases from \(-8\) to \(-10\).
## Step3: Check third table
For \(x\) values from \(-2\) to \(-1\), \(f(x)\) decreases from \(0\) to \(-3\). From \(-1\) to \(1\), \(f(x)\) increases from \(-3\) to \(3\). From \(1\) to \(2\), \(f(x)\) decreases from \(3\) to \(0\).
## Step4: Check fourth table
For \(x\) values from \(-2\) to \(-1\), \(f(x)\) increases from \(-10\) to \(-8\). From \(-1\) to \(1\), \(f(x)\) increases from \(-8\) to \(8\). From \(1\) to \(2\), \(f(x)\) increases from \(8\) to \(10\).
# Answer:
The first table shows a function that is decreasing only over the interval \((-1,1)\).
