Add 4.9 to each side so 4r>19.85 and divide both side by 4. So r> 4.96 so say any point over 5 and you are correct
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.
