You have the correct answer. The answer is choice D) Set of real numbers less than -1. Nice job.

As x approaches negative infinity, then -3^x approaches 0 though never actually gets there. So overall, f(x) approaches -1 as x approaches negative infinity. Plugging in x = 0 leads to f(x) = -2 which supports choice D.

If the if a cylinder is 7 in tall and has a volume of 63 Pi inches what is the area of the cross section it goes right down the

vitfil [10]

Answer: $9\pi \ in.^2$

Step-by-step explanation:

Given

The height of the cylinder is $h=7\ in.$

The volume of the cylinder is $V=63\pi \ in.^3$

The volume of the cylinder is the product of area and height

$\Rightarrow V=\pi r^2h\\$

Insert the values

$\Rightarrow 63\pi =A\times 7\\\\\Rightarrow A=\dfrac{63\pi}{7}\\\\\Rightarrow A=9\pi\ in.^2$

Thus, the area of the cross-section is $9\pi \ in.^2$

<h3>What is the graph of the parent function (y)?</h3>

The set of all coordinates (x, y) in the plane that satisfy the equation y = f(x) is the graph of the function. Suppose a function is only specified for a small set of input values, the graph of the function will only have a small number of points, in which each point's x-coordinate represents an input number and its y-coordinate represents an output number.

From the given information,

The domain for the $\mathbf{y=\sqrt{x}}$ is at x ≥ 0,
The range is the set of values that the dependent variable for which the function is defined. f(x) ≥ 0.
