What is the vertex of the function?
egoroff_w [7]
<h2>Explanation:</h2><h2></h2>

Here you haven't provided any function, so I'll assume this one:

f(x)=3x^2-18x+33

This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:

V(x,y) \\ \\ \\ x=-\frac{b}{2a} \\ \\ y=f(-\frac{b}{2a}) \\ \\ \\ where: \\ \\ \\ f(x)=ax^2+bx+c \\ \\ \\ So: \\ \\ a=3 \\ \\ b=-18 \\ \\ c=33

Therefore:

x=-\frac{(-18)}{2(3)}=3 \\ \\ f(3)=3(3)^2-18(3)+33=27-54+33=6

Therefore, the vertex is:

\boxed{V(3,6)}

WILL GIVE BRAINLIEST! DUE TODAY! WILL GIVE EVERYTHING GOOD!!! HELPP!!! I REALLY NEED HELP ON THIS ONE!!!!
PtichkaEL [24]

Answer:

So its pretty simple

The table provided the Xs so you can just substitute the x in the eqaution becuase the eqaution gives you Y and your looking for Y.

For the first one

-3/4*-16+3=y

12+3=15

So Y is 15

DO the same for the others

Also I think your rate of change is wrong, I think it’s -3/4 but your choice really, I might be wrong

You need to include how wide the walls are. but once you find how wide the walls are (X) then multiply it by how tall a the walls are (8 feet) and you will get the area of one wall. Take that answer and multiply it by 3 then multiply that by how much the paint costs
