To determine which of the following monomial function has a maximum value, you have to assume the value of x. Let us say the value of x is 2. Substitute 2 for all x’s in the monomial function.
y=-6x^3 = -6(2)^3 = -48
Answer:
[tex]y=-5x^4[/tex]
Step-by-step explanation:
Remember that a maximum value (global) of a function is the bigest value that the function takes.
For see the values of the functions you can see its graphs.
I have uploaded the graphs of the functions in the question and you can see it, and then convince yourself why the answer is y=-5x^4.
Also you have the fact that the functions of the form [tex]y=kx^n [/tex] have a maximum value only if [tex]n[/tex] is an even natural number and k is a negative real number.
