Answer:
f(x)=x
Explanation:
We are given with a table, Lets look at the value of x and y
The value of y is constantly increasing and the value of x is also increasing constantly. So it is a table for a linear equation.
the value of x and y are same, so the equation of the line is
y=x
when x=-2 the value of y=-2
when x=1 the value of y=1
Hence , the parent function is
