Question 1039192
Shifting the graph upwards by {{{4}}} units means that
for every value of {{{x}}}, the point {{{P(x,y)}}} will shift to a point {{{Q(x,y+4)}}} with a value of {{{y}}} that is {{{4}}} more.
Instead of the point {{{P(x,f(x))}}} in the original function graph,
the new graph will contain the point {{{Q(x,f(x)+4)}}} .
So, for any function {{{f(x)}}} , the equation for the function corresponding to the a graph shiftedr up by {{{4}}} is
{{{g(x)=f(x)+4}}} .
In the case of {{{f(x)=x^3}}} , the function for the shifted graph is
{{{g(x)=highlight(x^3+4)}}} .
