Answer:
A. {-1, 2, 7}
Step-by-step explanation:
For a set of ordered pairs, the domain is the set of first-numbers (x). The range is the set of second numbers (y, or g(x)).
The first step here is to find the g(x) values for each of the listed x-values.
The attachment shows a table.
Often, we like to list the domain and/or range values in numerical order, eliminating any duplicates. That is, the set of range values {2, -1, -1, 7} would be listed as ...
{-1, 2, 7} . . . . . . matches choice A
_____
You find the g(x) values by substituting for x and doing the arithmetic.
g(-2) = (-2)² -2 = 4 -2 = 2, for example
Answer:
0, 7, -10
Step-by-step explanation:
0, -7, 7, -10, -9, -10, 7, 0, 4
Two 0
one -7
Two 7
Two -10
one 4
0, 7, and -10 are the only ones to appear the most
Answer:
Y=7x+9
Step-by-step explanation:
Y=mx + b
b= y-intercept
m=slope
Substitute:
Y=7x+9
The answer is c. You distribute the X to the F and G. f(x) + g(x), which is x + 2.
Answer:
27 pages
Step-by-step explanation:
Since you read 3 pages on Monday and you read 3 times that number on Tuesday, the equation should be 3*3 to equal 9. Then, since you read 9 pages on Tuesday and 3 times that number on Wednesday, the equation should be 9*3 to equal 27 pages. So, on Wednesday, you read 27 pages in total.
