The first quartile of a data set is 51, and the third quartile is 71. Which value in the data set is an outlier? 20
40
80
100

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
