Fundamental Theorem of Algebra

If you have an 'n' degree polynomial, it has n roots with multiplicity.

f(x)=x^3

root =0 with multiplicity 3

f(x)=x^3+x^2+x

3 different roots

f(x)=x^2+5

0 real roots 3 imaginary ones

y=a+bx—>a is the y intercept, b is the slope.

Parameters- shift function up and down or left and right.

Used Excel to see how parameters affect the function.
