Question

Identify the monomial function(s) that have a minimum. y = 5x y = x3 y = –2x6 y = 4x4 y = 3x2 y = 2x6

Answer 1

y = 5x - This does not have a minimum.
y = x3 - This does not have a minimum
y = –2x6 - This does not have a minimum.
y = 4x4 - This has a minimum
y = 3x2 - This has a minimum
y = 2x6 - This has a minimum

Functions with the positive leading coefficient and even exponent will have a minimum

Answer 2

Answer:

tex]y = 4x^4[/tex]

$y = 3x^2$

$y = 2x^6$

Step-by-step explanation:

LEts check with each function

$y = 5x$ , it is a linear function.

Linear function does not have minimum

$y = x^3$, Cubic parent function does not have minimum

$y = -2x^6$, we have -2 (negative) . Leading coefficient is negative so, there will be a maximum

$y = 4x^4$,leading coefficient is positive so it have a minimum

$y = 3x^2$, leading coefficient is positive so it have a minimum

$y = 2x^6$, leading coefficient is positive so it have a minimum
