Which function is linear?
Q:
A:
A) f(x) = 5x2 + 10
B) f(x) =
5
x
+ 10
C) f(x) = 5x2 − 10
D) f(x) =
x
5
− 10

The Answer Is (D.

Step-by-step explanation:

f(x) =

x

5

− 10

A function is linear if it can be expressed in the form f(x)= mx + b or if its graph is a straight line.

f(x)= mx + b

f(x) =

x

5

− 10

f(x) =

1

5

x − 10

y = x + 95

y = 42 + 95

y=137 mm hg

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
