I have tried my best to solve these, working answers that are posted would be appreciated!! I want to see where im going wrong, if you could post your work it would be awesome.
1) -1/25d(d-40)
- What are the d intercepts?
- Find the vertex
- Write the function in standard form
2) h= -3/144(d-96)(d+96)
- What are the d intercepts?
- Find the vertex
- Write the function in standard form
3) y= 1/10x^2-2x
- What are the x intercepts
1) -1/25d(d-40)
- What are the d intercepts?
0 or 40
- Find the vertex
40/2 =20
D=20
h=-1/25d(d-40)
=-1/25(20)(20-40)
=-0.8(-20)
=16
VERTEX= (20,16)
- Write the function in standard form
2) h= -3/144(d-96)(d+96)
- What are the d intercepts?
- Find the vertex
- Write the function in standard form
3) y= 1/10x^2-2x
- What are the x intercepts

Thats as far as i got :C
