Question

function 3
linear
not linear
function 4
linear
not linear

Explanation:

Function 3

Step1: Recall linear function definition

A linear function has a graph that is a straight line (equation: \(y = mx + b\), constant slope).

Step2: Analyze Function 3's graph

Function 3’s graph is a curve (not a straight line), so it does not satisfy the linear function’s graphical property.

Function 4

Step1: Recall linear function definition

A linear function has a straight - line graph (constant slope, \(y=mx + b\) form).

Step2: Analyze Function 4's graph

Function 4’s graph is a curve with multiple bends, not a straight line, so it is not linear.

Answer:

s:

• For Function 3: Not linear (circle the "Not linear" option)
• For Function 4: Not linear (circle the "Not linear" option)
