Identify the monomial function(s) that have a maximum.

natima [27]

Answer:

Step-by-step explanation:

For a function f to have a maximum as per derivative rule we have to have

f'(x) =0, f"(x) <0

If second derivative =0 also then it is not maximum but point of inflections

Whenever f(x) = ax^n

we have

f'(x) = 0 gives x=0 and

f"(x) = n(n-1) ax ^(n-2)

So for n greater than or equal to there cannot be any maximum

And also for a straight line

y =-4x

y'=-4 and y"-0

No maximum

So only maximum can be for a funciton of the form y = ax^2

Here we do not have that all degrees are either 1 or greater than 1.

So no maximum for any funciton.

Can someone please help me? And it says “Solve each equation. Then, prove that your answer solves the original equation?

Viefleur [7K]

Step-by-step explanation:

We need to solve each equation.

a. 6c = 30

c = 30/6 = 5

2d-6=12

Adding 6 both sides

2d-6+6=12+6

2d = 18

d = 9

$\dfrac{x}{3}+9=2\\\\\dfrac{x}{3}=-7\\\\x=-21$

50=14+3m

50-14=3m

36=3m

m = 12

Hence, this is the required solution.
