Which of the following functions is not a linear function?
f(x) = -2
f(x) = 2 x
Of(x) = x2
f(x) = x - 2

Hello,

not linear function :

f(x) = -2

f(x) = x²

f(x) = x - 2

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
