The table of values has this data. For this data can you find an algebraic expression???????? By algebraic expression I Mean for example 10x+3 in order to get Y
X------l-------Y
0------------- 0
1--------------5
2------------ 20
3 ------------45
4 ------------80
5------------125

Well, y=5x^2 is the simplest, but I like:
y = -(1/4)x^6 + (15/4)x^5 - (85/4)x^4 + (225/4)x^3 - (127/2)x^2 + 30x
better.

This table doesn't represent a linear expression. If you graph it, you will *not* get a straight line. So, you can't use a simple expression in the form of y = mx + b to show the relationship. (And the person who thought it was y = 5x obviously didn't check past the first two rows in the table.)
Try y = 5 x^2
(or y = 5 x x )

You can't define something with an example. It's not clear what you really mean.

This seems to be a quadratic function. So, let
y = ax^2 + bx + c
a + b = 5
2a + b = 10
a = 5
b = 0
y = 5x^2

It's obviously a non-linear equation, jon got it right.
