**Unformatted text preview: **Quad rule My
Quadratic Function mightand
Highest exponent of x is 2
H(x ) = ax tbox+ c, where x 10
f(x/ =3 is a constant function
( x) = axto is a linear function
W
f(x ) = ax? +bxec is a Quadratic functor
FIX = ax3 abx' + extdis a Cubic funcion
Polynomial function : f(x) = an X"+ and talk
Where an, an 1, 9 4 - 21. ~ a, do are Graffiday
Example: F(X) = 2: constant
FCX 25 x 2 12 up 1 : Quadratic
D(x 26x 343 x- P 2x 15, cubic
Quadratic Function in the formn
f(X ) = a (x - h ) ? PK
positive the graph opens up
negative tho graph opens down
Example: f (x) z 2 (x-3)2+5
azz b=3 Res
2) Chik is the vertex
3 xzh gives axis of symmetry.
