Consider the function y=x^2+5x-2 . What would happen to the graph if (x + 5) was substituted in place of the x? A. The graph would shift 5 units to the right. B. The graph would shift down 5 units. C. The graph would shift up 5 units. D. The graph would shift 5 units to the left. Consider the function y=x^2+5x-2 . What would happen to the graph if (x + 5) was substituted in place of the x? A.

    and then find the roots after (x+5) is substitutes

    then it would be obvious that its been moved 5 to the left

    x+5=x-(-5) so, the graph will be valid if origin is taken (-5,0) instead of (0,0) so, the whole graph will shift in 5 units to left

    but finding the roots- method is not so good, i guess

    hmm, think it this way in the first case, the result u will get substituting x=0, in the 2nd case u will get that exact value for x=-5
