So... assuming f(x)=x^2-14x+44 then

 f(x)=x^2-14x+44\implies 
\begin{array}{lccclll}
\boxed{1}x^2&\boxed{-14}x&\boxed{+44}\\
\uparrow &\uparrow &\uparrow\\
a&b&c
\end{array}
\\ \quad \\
\textit{vertex of a parabola}\\ \quad \\
y = {{ \boxed{a}}}x^2{{ \boxed{+b}}}x{{ \boxed{+c}}}\\ \quad \\

\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)

Can someone please give me the answer to these two?
Radda [10]

Answer:

3: D - Undefined

4: A - 1

Step-by-step explanation:

For Question 3 your answer is D, undefined, because it does not have a slope, a slope is like a hill, but that just goes straight up, thus it is undefined.

For Question 4 your answer is A, 1, because it moves one digit to the right and then 1 digit up, Thus that is your answer.

I really need a good explanation on how to solve this, not just the answer please please please..
Alchen [17]

Answer:

Step-by-step explanation:

94

Mean = add all the numbers up and divide by how many numbers you added

So add (x +120  + 112 + 130 + 128 + 124 ) divided by 6  =118

x is the score you are looking for and 118 is the average he wants

so (x + 614 ) divided by 6 =118

now multiply both sides by 6

x + 614 = 118 times 6

x + 614 = 708

subtract 614 from both sides

x = 94
