Answer
Explanation:
Step1: Recall linear - function definition
A linear function has a graph that is a straight - line. Its equation is of the form $y = mx + b$, where $m$ and $b$ are constants.
Step2: Analyze Function 1
Function 1 has a V - shaped graph. It is not a single straight - line, so it is not linear.
Step3: Analyze Function 2
Function 2 has a horizontal straight - line graph. It can be written in the form $y=b$ (where $b$ is a constant), so it is linear.
Step4: Analyze Function 3
Function 3 has a curved graph. It is not a straight - line, so it is not linear.
Step5: Analyze Function 4
Function 4 has a wavy, curved graph. It is not a straight - line, so it is not linear.
Answer:
Function 1: Not linear Function 2: Linear Function 3: Not linear Function 4: Not linear
