Answer: Graph is below
=============================================================
Explanation:
We divide both sides by -4 to isolate p. This will flip the inequality sign.
-16 > -4p
-16/(-4) < -4p/(-4)
4 < p
p > 4
The graph has an open hole at 4 and shading to the right. See below.
Answer:
$513
Step-by-step explanation:
Find 9ft multiplied by 6ft, it is 54
Do $228 ÷ 54, which is equal to 4.2 repeated
Multiply 4.2 repeated by (13.5 × 9), = 513
Answer:
As the given equation represents a quadratic function.
Thus,
represents a function.
As we know that the function is just a relation in which each input has only one output.
Thus,
represents a relation and function.
Step-by-step explanation:
Given the equation
![y\:=\:x^2-9x](https://tex.z-dn.net/?f=y%5C%3A%3D%5C%3Ax%5E2-9x)
As the given equation represents a quadratic function.
Thus,
represents a function.
As we know that the function is just a relation in which each input has only one output.
Thus,
represents a relation and function.
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
![\mathrm{Domain\:of\:}\:x^2-9x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:](https://tex.z-dn.net/?f=%5Cmathrm%7BDomain%5C%3Aof%5C%3A%7D%5C%3Ax%5E2-9x%5C%3A%3A%5Cquad%20%5Cbegin%7Bbmatrix%7D%5Cmathrm%7BSolution%3A%7D%5C%3A%26%5C%3A-%5Cinfty%20%5C%3A%3Cx%3C%5Cinfty%20%5C%5C%20%5C%3A%5Cmathrm%7BInterval%5C%3ANotation%3A%7D%26%5C%3A%5Cleft%28-%5Cinfty%20%5C%3A%2C%5C%3A%5Cinfty%20%5C%3A%5Cright%29%5Cend%7Bbmatrix%7D)
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
![\mathrm{Range\:of\:}x^2-9x:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:-\frac{81}{4}\:\\ \:\mathrm{Interval\:Notation:}&\:[-\frac{81}{4},\:\infty \:)\end{bmatrix}](https://tex.z-dn.net/?f=%5Cmathrm%7BRange%5C%3Aof%5C%3A%7Dx%5E2-9x%3A%5Cquad%20%5Cbegin%7Bbmatrix%7D%5Cmathrm%7BSolution%3A%7D%5C%3A%26%5C%3Af%5Cleft%28x%5Cright%29%5Cge%20%5C%3A-%5Cfrac%7B81%7D%7B4%7D%5C%3A%5C%5C%20%5C%3A%5Cmathrm%7BInterval%5C%3ANotation%3A%7D%26%5C%3A%5B-%5Cfrac%7B81%7D%7B4%7D%2C%5C%3A%5Cinfty%20%5C%3A%29%5Cend%7Bbmatrix%7D)
The graph is also attached below. From the graph, it is clear that it represents a Parabola.
