Question

Which parent function is represented by the table x=-2,-1,0,1,2 y=-2,-1,0,1,2

Answer 1

If you take a look at the table values and notice that y values are the same as x values, then the parent function is y=x

Answer 2

This would be the function f(x) = x.

Explanation:

Every y-coordinate is the same as its corresponding x-coordinate. This means that the function maps every x to the y of the same value; this gives us

f(x) = x.
