Which of the following equations is a constant function? y = x y = 5 x = 5
Mamont248 [21]

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

Help please? its an exam
poizon [28]

Answer:

Option 2

Step-by-step explanation:

In ΔABC,

AD is a median and point M is the point of concurrence of all medians.

Therefore, point M is a centroid of the triangle.

And M will divide line AD in the ratio of 1 : 2 (Ratio of AM : MD)

Since, length of MD = 2 cm

Therefore, length of AM = 4 cm

Total length of AD = AM + MD

                               = 2 + 4

                               = 6

Option 2 will be the answer.
