Question

which of the following properties are used to compare two non-linear functions?
i. slope
ii. graph
iii. roots
iv. maximum and minimum

• ii, iii, and iv
• i, ii, and iii

Explanation:

Analyze the concept of slope for non-linear functions

Slope is a constant property unique to linear functions. For non-linear functions, the rate of change is not constant, meaning they do not have a single "slope" to compare them directly. Thus, property I is not a standard property used to compare two non-linear functions.

Evaluate the remaining properties

• II. Graph: Visualizing and comparing the graphs of non-linear functions helps identify their shapes, behaviors, and key features.
• III. Roots: Comparing the roots (x-intercepts) shows where each non-linear function intersects the horizontal axis.
• IV. Maximum and Minimum: Comparing the extrema (vertices, local/global maximums or minimums) is a fundamental way to analyze and compare non-linear behaviors.

Determine the correct combination

Since properties II, III, and IV are valid and standard properties used to compare non-linear functions, the correct combination is II, III, and IV.

Answer:

• II, III, and IV (Correct answer)
• I, II, and III
