Answer:

$f(x)=\sqrt{x-1}$

Step-by-step explanation:

Hello there!

I take it you are asking for the expression of the function shown.

Since it is a normal square root function moved 1 unit to the right, you will subtract 1 from x.

Answer:

y = √(x - 1)

Step-by-step explanation:

We start with the basic square root function, whose domain is [0, ∞ ]. The given graph is that of this basic square root function, EXCEPT that the whole graph has been translated 1 unit to the right.

The graph shown is that of y = √(x - 1).

First question.

We will build up the 3-dimensional object from the dimensions shown in the view above. In doing this, the object is as shown in figure 1. So, we need to find the volume of this object. Let's cut off this object into two objects, so in doing this we can find the whole volume as the sum of the volume in green plus the volume in red (both are cubes), so:

$V_{t} = V_{g}+V_{r} = 8 \times 3 \times 5 + 8 \times 5 \times 8 = 440 ft^{3}$

So the answer is G.

Second question

The answer is D. Let's analyze it:

Given that r represents the radius of the pizza and n the number of slices, so if we substitute r in this equation, then the values for n are:

$n = r^{2}+1$

$n=2^{2}+1=5$
$n=4^{2}+1=17$
$n=5^{2}+1=16$
$n=8^{2}+1=65$
$n=10^{2}+1=101$

These are the values of n shown in the table above.
