Idon't know how to do this.
3. apply your knowledge of factoring and zero product property to write a quadratic function when given -2 and 2/3 as the zeros. (show all work for full credit)

3x^2 +4x-4

Step-by-step explanation:

We know the zeros are  -2 and 2/3

Using the zero product property

(x- -2) (x -2/3) = 0

(x+2) (x-2/3) = 0

We want to write the function, so we need to FOIL

first x*x = x^2

outer: -2/3x

inner: 2x

last: -4/3

Add together

x^2 -2/3x +2x -4/3 =0

x^2 -2/3x+6/3x -4/3 =0

x^2 +4/3x - 4/3 =0

We can multiply by any constant and it will still give us the same zeros

I will multiply by 3 to get rid of the fractions

3(x^2 +4/3x - 4/3) =0*3

3x^2 +4x-4 = 0

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
