The product of -5 and -4 is 20
The square of the smaller number, -5, is 25.
The product, 20, is indeed 5 less than 25, the square of the smaller number.</span>
We have to determine if the functions are linear or not.
We can do this by rearranging the equations in this form:

where m and b are constants.
<em>NOTE: There are many ways to prove that a function is linear, but this is the easiest for this question. </em>
36.

As this function can not be written in the form y=mx+b, then it is not linear.
37.

This function is now in the form y=mx+b, where m=3/4 and b=-15. Then, this function is a linear function.
Answer:
36. Non-linear.
37. Linear.
Answer:
The required function is F(x) = tanx - 2.
Step-by-step explanation:
We all know the graph of tanx ,
The graph of tanx passes through the origin and repeats in the interval of π.
Now , after looking into the graph we can clearly say that it is the shifted graph of tanx , Which is shifted in the -y direction .
Thus ,
It is clear that F(x) must be like F(x) = tanx - c , where c is a positive constant .
Also, At x = 0 , Value of the function is coming out to be -2 ,
Putting x = 0 in F(x) = tanx - c , we get , F(x) = -c .
Thus c = 2.
So, the required function is F(x) = tanx - 2.
