Across
- 4. X=-b/2a
- 7. Change to x^2+bx=C then multiply by (b/2)^2
- 9. open down/ concave down and the vertex is the maximum/highest point a<0
- 10. (h,k)
- 11. Ax+By=C
- 14. open up/ concave up and the vertex is the minimum/lowest point a>0
- 15. Exponents: move exponent to the denominator and mak it positive
- 16. y-y1=m(x-x1)
Down
- 1. Y=mx+b
- 2. Exponents: multiply exponents
- 3. F(x)=a(x-h)^2 + k
- 5. Exponents:add the exponents
- 6. multiply the denominator and numerator by a radical
- 8. part of the quadratic formula that determines the amount of solutions b^2 -4ac
- 12. A ratio including units usually "per"
- 13. Rise over run
