Question

the graph of $f(x) = x$ is known as the select choice in a family of linear graphs.

Explanation:

In the family of linear functions (which have the form \( f(x)=mx + b \), where \( m \) is the slope and \( b \) is the y - intercept), for the function \( f(x)=x \), we can rewrite it as \( f(x)=1x+0 \). The parent function of a linear function family is the simplest form of the linear function, and \( f(x) = x \) (with slope \( m = 1 \) and y - intercept \( b=0 \)) is the parent function for the family of linear graphs.

Answer:

parent function
