Vertexs Flashcards
1
Q
How do you calculate logarithmic terms manually?
A
- Enter value of X
- Press ln
2
Q
What is the vertex formula?
A
V = -b / (2 * a)
3
Q
How do you complete a vertex?
A
- Plug in appropriate betas
- a = coefficient with a square
- b = coefficient without a square
4
Q
What effect does the beta have on the shape of parabola and interpret?
A
- Positive Beta for Ax2 = Min T.P => effect of X is negative until vertex then effect is positive
- Negative Beta for Ax2 = Max T.P => effect of X is positive until vertex then effect is negative
