Algebra I

Step-by-step explanation:

Step 1: Define

Identify

f(x) = 4x + 1

g(x) = x² - 5

(f + g)(x) = f(x) + g(x)

Step 2: Find

B  

Step-by-step explanation:  6  18  11  18

f(x)=4x+1 and g(x)=x^2 -5

f(x)=     4x+1

g(x)=x^2 -5      just add these two equations

(f+g)(x)  =  x² + 4x +1 - 5

(f+g)(x)  =  x² + 4x - 4     B

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
