Answer:

Second Option

y = 5

Step-by-step explanation:

A constant function is one for which the range does not change regardless of the value of the domain.

f (x_1) = f (x_2) = f (x_3) = m

Where m is a constant.

The constant functions are horizontal lines parallel to the axis of the x

Note that

y = x is not a constant function because the value of y changes when x changes.

x = 1, y = 1

x = 2 y = 2

x = 5 is not a constant function because the range of the function is not constant. x = 5 is a vertical line

y = 5 is a constant function, since for any of the value of x, the value of y will always be 5

1+4=5 2+5=12 3+6=21 8+11=?
g100num [7]
I think the pattern is that you multiply the first number by the second , then add the first number. SO:
e.g. for the first one 1 x 4 = 4 , 4 + 1 = 5
for the second one 2 x 5 = 10, 10 + 2 = 12...
So for 8+11:
you do 8 x 11 = 88 , 88 + 8 = 96
