Which function is nonlinear
2 answers:
Answer:
Only 3rd one is exponential and non linear.
Step-by-step explanation:
Linear functions are in the form of and have a constant slope.
Nonlinear functions have a slope that varies between points.
Also, the linear functions are polynomials with highest exponent equal to 1 and all others are non linear.
Here, only option 3rd is not linear or non linear.
Other options are all in the form of means linear.
Only 3rd one is exponential and non linear.

Answer:
<h2>Kelly is wrong, with this congruent parts, we can conclude that triangles are congruent.</h2>Step-by-step explanation:
To demonstrate congruent triangles, we need to use the proper postulates. There are at least 5 postulates we can use.
- Angle-Angle-Side Theorem (AAS theorem).
- Hypotenuse-Leg Theorem (HL theorem).
- Side-Side-Side Postulate (SSS postulate).
- Angle-Side-Angle Postulate (ASA postulate).
- Side-Angle-Side Postulate (SAS postulate).
In this case, Kelly SAS postulate, because the corresponding sides-angles-sides are congruent, i.e., KL ≅ MN and LM ≅ KN, also, all corresponding angles are congruent.
So, as you can see, only using SAS postulate, the congruency can be demonstrated. (Refer to the image attached to see an example of SAS postulate)
