<h2>Answer:</h2>

The equation of the given graph is:

$y=-(x-3)^2+1$

<h2>Step-by-step explanation:</h2>

We know that the general equation of a downward parabola with vertex at (h,k) is given by the formula:

$y=a(x-h)^2+k$

where a<0

Here in each of the options we have a= 1 or -1

but as a has to be less than 1 this means that a= -1

Also, we have: (h,k)= (3,1)

i.e. h=3 and k=1

Hence, putting the values of h,k and a in the general equation we get:

Hence, the equation of parabola is:

$y=-(x-3)^2+1$

What is -4R-2r+5 as a simpler exspression

enyata [817]

$\sf-4R-2r+5$ is already in simplest form.

But if you meant to say $\sf-4r-2r+5$ , we would combine the first two terms.

Adding/subtracting like terms is the same as adding/subtracting whole numbers.

$\sf-4-2=-6$

Therefore:

$\sf-4r-2r=-6r$

Which gives us:

$\boxed{\sf-6r+5}$
