## mandy17 4 years ago 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 .

1. menoldon

A

2. Arnab09

option D

3. menoldon

oopsie its is D

4. shaik0124

EXPLAIN HOW U GOT D ANSWER

5. menoldon

first find roots

6. menoldon

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

7. menoldon

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

8. shaik0124

WHAT EQN DID U GOT

9. menoldon

15x^4-20x^3+10x^2-35x

10. menoldon

thats with x+5 substituted

11. Arnab09

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

12. menoldon

it actually x^2+15x+48

13. menoldon

after x+5 is substituted

14. shaik0124

I GOT THE EQN X^2+15X-47

15. menoldon

no its +48

16. menoldon

not -47

17. shaik0124

YA =48

18. Arnab09

why u guys r fighting on it?? :)

19. mandy17

Which of the following describes the non-rigid transformation in the function shown below? y+5=-2(x-1)^2 A. The graph is reflected across the x-axis. B. The graph is shifted 1 unit right. C. The graph is shifted 5 units down. D. The graph is stretched vertically by a factor of 2.

20. menoldon

im just saying the right answer not fighting

21. Arnab09

ok, ok :D

22. Arnab09

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

23. menoldon

is there a better way?

24. Arnab09

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

25. menoldon

oh ok
