Question

What happens to a graph when you subtract 3 from f(x)?

Answer 1

Y-intercept, where the graph increases/decreases, end behavior, etc

Answer 2

Subtracting 3 from the graph of f(x) will shift the whole graph downward by 3 units Thus, the y-intercept changes, but everything else stays the same. Look up "vertical translation."
