Idont understand anything about my math !
the function g(x) is a shift of the function f(x) = 7x. using the table, choose the correct expression for g(x).
x / g(x)

0 / -7
1 / 0
2 / 7
3 / 14
4 / 21
(the slashes are spaces since i cant put a table on here and it puts them together without them)
a. f(x) + 1
b. f(x - 1)
c. f(x + 1)
d. f(x) - 1

Will give the box plots below show the math scores of students in two different classes: class a 55 72 75 89 95 class b 55 70 75 94 100 based on the box plots, which statement is correct? a: the median score of class a is greater than the median score of class b. b: the lower quartile of class a is greater than the lower quartile of class b. c: the upper quartile of class a is greater than the upper quartile of class b. d: the maximum score of class a is greater than the maximum score of class b.
