Answer:

  f(f(n)) = -n^4 -8n^2 -20

Step-by-step explanation:

As with any function evaluation, you substitute the argument for the variable and simplify.

  f(f(n))=f(-n^2-4)=-(-n^2-4)^2-4\\\\=-(n^4+8n^2+16)-4\\\\\boxed{f(f(n))=-n^4-8n^2-20}

Without drawing the graph of the equation, determine how many points the given equation have in common with the x-axis and where
Gala2k [10]
Remark
It's asking you to complete the square to find the vertex. 

Solve
y = -2x^2 + x + 3 Put brackets around the first 2 terms.
y = (-2x^2 + x) + 3    Pull out the 2.
y = -2(x^2 - 1/2 x) + 3 Be especially observant of the sign on 1/2x Divide the middle term's number by 2 and square it. 
y = -2(x^2 - 1/2 x + [(1/2) / 2]^2 ) + 3 [1/2 divided by 2 is 1/4. (1/4)^2 = 1/16; 2*(1/16) = 1/8
y = - 2(x^2 - 1/2 x + (1/4)^2 ) + 3 + 1/8
y = -2(x - 1/4)^2 + 3 1/8

Comment
Answer to your question. The maximum value (3 1/8) is above the y axis. That means the graph of the equation crosses the x axis twice. I'm going to include the graph because in answering the question, there is no harm in seeing the graph.

Which ordered pair would form a proportional relationship with the point graphed below?
kvasek [131]

Answer:

(x,y) = (-30,10)

Step-by-step explanation:

Given

(x,y) = (60,-20)

Required:

Determine a pair with a proportional relationship

A proportional relationship is:

k = \frac{y}{x}

Where k is the constant of proportionality.

(x,y) = (60,-20)

So, we have:

k = \frac{-20}{60}

k = -\frac{1}{3}

This means that for a pair to have a proportional relation, k must be -1/3.

This is true for (c).

Where:

(x,y) = (-30,10)

So, we have:

k = \frac{10}{-30}

k = -\frac{1}{3}
