## surryyy one year ago Given the graph below, which of the following points would be included in the graph of the inverse of the function? Choose all that apply. (1, 0) (0, 1) (-2, 1) (1, 2)

2. anonymous

01, iinverse ii2 the 2ame a2 rever2e

3. anonymous

2orry iif iim not correct though .-.

4. imqwerty

1st-we will write the equation of this graph

5. imqwerty

so we choose 2 points which lie on it and then we'll use double point form - $\frac{ y-y _{1} }{ y _{2 }-y _{1}}=\frac{ x-x _{1} }{ x _{2}-x _{1}}$where (x1,y1) and (x2,y2) are the 2 points which lie on the graph :)

6. imqwerty

so the 2 points which i chose are -(0,1) and (1,-2) substituting the values we get-

7. imqwerty

(y-1)/(-2-1)=(x-0)/(1-0) (y-1)/-3 = x y-1=-3x y=1-3x <-----equation of given graph

8. imqwerty

to find the equation of the inverse of this graph we just need to switch y and x

9. imqwerty

so the equation which we get is- x=1-3y <-----equation of inverse of the given graph

10. imqwerty

now u just need to try the options ..........put them in the equation nd if they satisfy then they lie on this inverse graph :)

11. surryyy

So its (1, 0) and (-2, 1)

12. imqwerty

yes :)

13. surryyy

Thanks! :)

14. imqwerty

no prblem :D
