With the exception of the form f(x) = ax + b, non-linear graph equation can take any form.See graph in photo attached.
<h3>What is non linear function and its graph?</h3>As the name suggests, a nonlinear function is one that is NOT linear.
To put it another way, a nonlinear function's graph is not a linear. In other words, its graph is not limited to being a line.
Any function whose graph is not a straight line should be considered a nonlinear function since a nonlinear function is one that is NOT linear.
Since none of the graphs in the following figure are straight lines, they all illustrate nonlinear functions.

Answer:
It will take them approximately 51.43 minutes to complete the project together
Step-by-step explanation:
This is what is called a "shared job" problem.
The best way to work on them is to start by finding the "portion" of the job done by each of the people in the unit of time.
So, for example, Sarah completes the project in 90 minutes, so in the unit of time (that is 1 minute) she completed 1/90 of the total project
Betty completes the project in 120 minutes, so in the unit of time (1 minute) she completes 1/120 of the total project.
We don't know how long it would take for them to complete the project when working together, so we call that time "x" (our unknown).
Now, when they work together completing the entire job in x minutes, in the unit of time they would have done 1/x of the total project.
In the unite of time, the fraction of the job done together (1/x) should equal the fraction of the job done by Sarah (1/90) plus the fraction of the job done by Betty. This in mathematical form becomes:
So it will take them approximately 51.43 minutes to complete the project together.
