Determine the rule of a quadratic function in factored form given the following information:
.
the zeros are (-2,0) and (4,0)
it passes through the point (5,14)
.

Step-by-step explanation:

Hi there!

Factored form: where r and s are two zeros

Given that the zeros are (-2,0) and (4,0), we know that -2 and 4 are r and s in the above equation. Plug these in:

Now, to solve for a, plug in the given point (5,14) as (x,y):

Therefore, a=2. Plug this back into the original equation:

I hope this helps!

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
