Write an algebraic expression for "add 2 to n then square the result."

(n + 2)^2.

Step-by-step explanation:

(n + 2)^2.

2 is added to n, then the result  'n + 2' is squared. We need to put parentheses around the n + 2 to indicate that the whole expression is squared.

d is correct

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
