Answer:
No restriction
Domain:
![(-\infty,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%5Cinfty%29)
Step-by-step explanation:
We are given function as
![f(x)=e^{x+4}+7](https://tex.z-dn.net/?f=f%28x%29%3De%5E%7Bx%2B4%7D%2B7)
we know that this is exponential function
and x+4 as an exponent over e
so, we can select any real values of x as an exponent
and this function will be defined for all values of x
so, there won't be any value of x where f(x) is undefined
So, domain would be
![(-\infty,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%5Cinfty%29)
Answer:
59
Step-by-step explanation:
z-28+2z+31=180 (angle sum property of a triangle)
3z +3 =180
3z=177
z=177/3
therefore z=59
Answer:
The answer should be c
Step-by-step explanation:
whenever you are trying to determine whether a graph determines a function or not, just draw a vertically straight line through the graph's line. If you draw that line and it goes through the graph's line more than once, then the graph does not represent a function.
Answer: A, D
Step-by-step explanation:
A) Correct.
. Similar logic for y.
B) Incorrect. The numerators are different.
C. Incorrect. The denominators are not the same.
