Final answer:
The x-intercepts of the graph of y = f(x+3) are -1 and 9.
Step-by-step explanation:
The x-intercepts of the graph of y = f(x) are -4 and 6. To find the x-intercepts of the graph of y = f(x+3), we need to substitute x+3 into the equation and solve for x.
Substituting x+3 into the equation, we get y = f(x+3) = f((-4)+3) = f(-1) and y = f(x+3) = f((6)+3) = f(9). Therefore, the x-intercepts of the graph of y = f(x+3) are -1 and 9.
