## anonymous 3 years ago Need help on a Algebra 2 Honors Question!

1. anonymous

4.f(x)= -1 if x ≤ -6 5 if -6 < x ≤ -2 2x + 9 if x > -2 (1 Point)

2. anonymous

I also have part of a table filled out

3. anonymous

4. anonymous

I just don't understand what I am supposed to do for the first 4 columns.

5. anonymous

if i was good at this ill help but me im not that good

6. anonymous

I just know about the las column never did any like the first two. I could post other I have already done.

7. anonymous

8. anonymous

like what r u suppose to do?

9. anonymous

plug in numbers for coordinates and graph it.

10. anonymous

Example fx=2x+9 if x > -2

11. anonymous

Next you would chose a value for x that is greater than -2 which is 0

12. anonymous

oh i have no idea but i can ask my bro to help u

13. anonymous

so now its 2(0)+9 which gives us 9 if we solve it and that is our y value

14. anonymous

ok...

15. anonymous

giving us the coordinates for a point at (0,9) if we do a few more we get a graph for two of the columns

16. anonymous

I just don't now what to do if there is no x value for the equation.

17. anonymous

yeahh im confused on the same thin ur talkin bout o dont get it either

18. Blacksteel

This function works just like any other in the other two sections. For -6 < x < -2, the function is just y = 5, so for any x value in that range you'll get 5 as your result. Similarly, for any x < -6, y = 1.

19. anonymous

so any number would be -1 for the first two columns

20. Blacksteel

For the first two columns, you'll want to use different x values, but the y value will always be -1. So for example, the first two columns might look like: $\left[ -6 | -1 \right]$$\left[ -7 | -1 \right]$$\left[ -8 | -1 \right]$

21. anonymous

and the graph would be a horizontal line on y=-1 right

22. Blacksteel

Yes.

23. anonymous

thanks a lot I relly needed help understanding this and this is the only question that did those with nothing in the lesson that talked about it. Thanks again
