Question

write a polynonmial function in standard form with the given zero's x= -2,0,1

Answer 1

hint:
If a function has 0 at x=a, x=b and x=c, it can be writen as f(x)=(x-a)(x-b)(x-c)
now multiply the terms in paréntesis and you get the standart form

Answer 2

f(x)=x-(-2)(x-0)(x-1)

Answer 3

lie that

Answer 4

f(x)=(x+2)(x-0)(x-1)

Answer 5

now, multiply the parentesys

Answer 6

x^2+2x

Answer 7

hmm, let's do it step by step.
f(x)=(x+2)(x-0)(x-1)=x(x+2)(x-1)=(x^2+2x)(x-1)=x^3-x^2+2x^2-2x=x^3+x^2-2x

Answer 8

is the bottom one the answer

Answer 9

yes

Answer 10

thanx :).....do u think u could help me on a a couple moree
