3. x y y = mx + b y = ax 2 + bx + c f(x) = sin x g(x) = e x f(x) = ln (x+5)

6. y = mx + b slopey-intercept y = 2x + 3 y = 3x - 4 y = -(1/2)x

7. y = 4 x = 2

8. y = ax 2 +bx + c y = x 2

9. y = x 2 - 2x + 1

10. y = x 2 - 2x + 2

11. + - or y = x 2 y = -x 2

12. changes width of parabola y = x 2 y = 2x 2 y =.5x 2

13. moves parabola up or down y = x 2 + 2x + 1 y = x 2 + 2x y = x 2 + 2x - 1

14. y = x 2 + 2x + 1 y = (x+1) 2 + 2(x+1) + 1

15. y = x 2 + 2x + 1 y = (x+1) 2 + 2(x+1) + 1

16. y = ax 2 + bx + c y = (x+h) 2 + (x+h) + c y = ± x 2
