it cant be solved but there is an infinite ways this could be taken
( - 6, 0).(2, 0 ) , vertex = ( - 2, - 16)
to find the x-intercepts set f(x) = 0
x² + 4x - 12 = 0
(x + 6)(x - 2) = 0 ( equate each factor to zero and solve for x )
x + 6 = 0 ⇒ x = - 6
x - 2 = 0 ⇒ x = 2
x- intercepts are ( - 6, 0),(2, 0)
given the quadratic in standard form : y = ax² + bx + c
the x-coordinate of the vertex = - 
here a = 1 , b = 4 and c = - 12
x- coordinate of vertex = - 
= - 2
substitute this value into the equation for y-coordinate
x = - 2 → y = 4 - 8 - 12 = - 16
vertex = ( - 2, - 16)
Answer:
I think the answer is B. $12.55
Step-by-step explanation:
14.50 - 6.95 = 7.55
7.55 + 5 = 12.55
The answer is quadratic.
A quadratic equation takes this form:
<em>ax^2+ bx + c</em>
The "a,""b,"and "c" represent numerical coefficients.
This is how your equation looks:
3x + x^2 + 4
Now it is standard that we organize the polynomial in descending order so it will look like this:
x^ 2 + 3x + 4
(commutative property of addition says that the arrangement will not affect the result)
It matches the quadratic polynomial form.
<em>* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed. </em>
