Question

True or False The average rate of change of $f\left(x\right)=2x+8$is$8.$

Short answer

The given statement is false.

Step-by-step solution

Step 1. Given information

Given that function is$f\left(x\right)=2x+8.$

Step 2. Solution

Since, we know that if $y=mx+b$be a function then the average rate of change is $m.$

Here, function is $f\left(x\right)=2x+8,$so the average rate of change is $2.$

Step 3. Final answer

Hence, the given statement is false.
