x y

y = mx + b

y = ax2 + bx + cf(x) = sin x

g(x) = ex

f(x) = ln (x+5)

y = mx + b

slope y-intercept

y = 2x + 3

y = 3x - 4

y = -(1/2)x

y = 4

x = 2

y = ax2 +bx + c

y = x2

y = x2 - 2x + 1

y = x2 - 2x + 2

+ -or

y = x2

y = -x2

changes width of parabola

y = x2

y = 2x2

y = .5x2

moves parabola up

or downy = x2 + 2x + 1

y = x2 + 2x

y = x2 + 2x - 1

y = x2 + 2x + 1

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

y = x2 + 2x + 1

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

y = ax2 + bx + c

y = ax2 + bx + c

y = (x+h)2 + (x+h) + c

y = ± x2
