To solve the equation: sqrt(x) = m
Take the square of both sides to have (sqrt(x))^2 = m^2
=> x = m^2
Yes, the table represents a function.
None of the independent (x) values are repeated and each one has a corresponding (y) value.
If you had a repeated (x) value in the table, it would not represent a function.
So the easiest way to solve this is to use the straight line provided .
180=90+61+x
180=151+x
29=x
