Answer:
c 10.5
Step-by-step explanation:
just multiply 10.5 × 3
To find the function that has the following end behavior:
![\begin{gathered} f(x)\rightarrow-\infty\text{ as }x\rightarrow\infty \\ f(x)\rightarrow\infty\text{ as }x\rightarrow-\infty \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%5Crightarrow-%5Cinfty%5Ctext%7B%20as%20%7Dx%5Crightarrow%5Cinfty%20%5C%5C%20f%28x%29%5Crightarrow%5Cinfty%5Ctext%7B%20as%20%7Dx%5Crightarrow-%5Cinfty%20%5Cend%7Bgathered%7D)
Considering the function which is given in option C.
When x tends to infinity,
![\begin{gathered} f\mleft(x\mright)=-x^3-4x^2+x \\ \lim _{x\to\infty}(-x^3-4x^2+x)=-\infty \\ \lim _{x\to-\infty}(-x^3-4x^2+x)=\infty \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%5Cmleft%28x%5Cmright%29%3D-x%5E3-4x%5E2%2Bx%20%5C%5C%20%5Clim%20_%7Bx%5Cto%5Cinfty%7D%28-x%5E3-4x%5E2%2Bx%29%3D-%5Cinfty%20%5C%5C%20%5Clim%20_%7Bx%5Cto-%5Cinfty%7D%28-x%5E3-4x%5E2%2Bx%29%3D%5Cinfty%20%5Cend%7Bgathered%7D)
In other words, the degree of the given function is 3.
That is, odd.
The leading coefficient is -1.
That is, negative.
Hence, the end behavior is,
![\begin{gathered} f(x)\rightarrow-\infty\text{ as }x\rightarrow\infty \\ f(x)\rightarrow\infty\text{ as }x\rightarrow-\infty \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20f%28x%29%5Crightarrow-%5Cinfty%5Ctext%7B%20as%20%7Dx%5Crightarrow%5Cinfty%20%5C%5C%20f%28x%29%5Crightarrow%5Cinfty%5Ctext%7B%20as%20%7Dx%5Crightarrow-%5Cinfty%20%5Cend%7Bgathered%7D)
Hence, the correct option is C.
Answer:
7 and 4
Step-by-step explanation:
If you set up a rectangle you get an area of 28 cm^2
4x7=28
the base is 7 cm
the height is 4 cm
