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

Answer:

tan cox³ / 5s

Replace ^-1 with ^(-1)

Replace x3 with x³

<h3>Step 1</h3>

Simplify

x³ / 5

Use equation to solve

tan • ((co • (s-1)) • x³ / 5)

<h3>Step 2</h3>

Take the previous equation and format it in a simpler form

tan • ((co • (s-1)) • x³ / 5) ⇒ tan • cox³ / 5s

<h3>Result</h3>

tan cox³ / 5s
