Answer:
Domain: {1, 2, 3, 4}
Range: {3, 6, 9, 12}
Step-by-step explanation:
In a function the domain represents the values of 'x' and the range represents the values of 'y'. For any given set of points, they are in the form of (x, y). So the domain would be the 'x' value in each point and the range is the 'y' value for each point:
Domain: {1, 2, 3, 4}
Range: {3, 6, 9, 12}
In this question, we're solving the expressions.
Problem 1:
For problem 1, f(x) + g(x) means that we're combining both of the equations together by adding.
Solve:
3x + 2 + x - 3
Combine like terms:
4x + 2 - 3
Answer to problem 1: 4x - 1
Problem 2:
In this problem, you're getting both of the expressions and combining them; however, you would need to plug in -1 to the x variable in both of the expressions.
Your problem should look like this:
3(-1) + 2 - 1 - 3
Solve:
3(-1) + 2 - 1 - 3
-3 + 2 - 1 - 3
-1 - 1 - 3
-2 - 3
-5
Answer to problem 2: -5
hmmm a line with a slope of 0 is a horizontal one, and it has no slope-intercept form.

Answer:
A
Step-by-step explanation:
The n th term formula for a geometric sequence is
= a
where a is the first term and r the common ratio
here a = - 5 and r = - 10 ÷ - 5 = 2, thus
= - 5( → A
