A student graphed the linear parent function f\left(x\right)=xf(x)=x and g\left(x\right)=x+3g(x)=x+3 on the same coordinate grid. Which statement describes how the parent function f\left(x\right)=xf(x)=x and g\left(x\right)=x+3g(x)=x+3 are related? A. The graph of the linear parent function is shifted 3 units down to create the graph of g

B. The graph of the linear parent function is shifted 3 units up to create the graph of g.

C. The graph of the linear parent function is steeper than the graph of g

D. The graph of the linear parent function is less steep than the graph of g.
