(A), (D), and (E)
Step-by-step explanation:
In a quadratic function, the solutions are always on the x-axis, which means that it can be another word for x-intercept. Also, a zero and a root are the same thing, and they are both x-intercepts. Hope this helps!
Answer:
h'(1)=0
Step-by-step explanation:
We use the definition of the derivative of a quotient:
If
, then:

Since in our case we want the derivative of
at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

which, by replacing with the given numerical values:

becomes:

Answer:
I think it would be -4x-6y+12
Answer:

Step-by-step explanation:
The given equation is
...........(i)
we know the formula i.e.

Applying this formula on equation (i) gives
= 
Opening the sqaure gives and canceling
with 2 gives us
= 
= 
which is the answer
