Your answer would be C and D, the domain for this function is all real numbers, and the range for this function is the set {-5}.
C is correct: The domain of a function is the amount of x values. For example, if you had a line going from an x value of 1 to an x value of 3, the domain would be {1<x<3}.
In this case, C is stating the domain of this function is all real numbers. This is true, because the straight line will continue for all values of x, so therefore the domain is all values of x, or all real numbers.
D is correct: The range is the exact opposite of a domain of a function. It is the number of y values the function covers.
In this case, D is stating the range is {-5}. This is correct, because the straight line only covers the y value of -5, so therefore that is the range.
A is therefore incorrect because the domain has already been established as all real numbers. B is incorrect because a horizontal line is a function, and one value of y can have multiple values of x. E is incorrect because the range has already been established as only one number.
Good luck!
(3.48 x 10^3) x (9 x 10^4) + (9.9 x 10^8)
(3480) x (90000) + (990000000)
(313200000) + (990000000)
1303200000
1.3032 x 10^9
Hope this helps!
Answer:
2!
Step-by-step explanation:
2nd one since it's the only the negative one after multiplying, others will become positive, since there are two negatives which cancels!

Answer:
This is true when f is less than 83 and false when f is equal to or greater than 83
Step-by-step explanation:
67>f-15
Add 15 to each side
67+15>f-15+15
83 > f
This is true when f is less than 83 and false when f is equal to or greater than 83
