F(n)=4n <br> g(n)=n2+2n <br> find f(g(-6))

ELEN [110]

Answer:

When f(n) = 4n and g(n) = n² + 2n, f(g(-6)) = 96.

Step-by-step explanation:

To evaluate f(g(-6)), first find g(-6).

g(n) = n² + 2n

Substitute value.

g(-6) = (-6)² + 2(-6)

Square -6. Remember that (-x)² = x²

g(-6) = 36 + 2(-6)

Multiply 2 and -6.

g(-6) = 36 - 12

Subtract 12 from 36.

g(-6) = 24.

Now knowing this, substitute that value into f(n).

f(g(-6)) = f(24)

f(n) = 4n

Substitute value.

f(24) = 4(24)

Multiply 4 and 24.

f(24) = 96.

$- 0.6 \leqslant x \leqslant 0.666 \: and \: x > \sqrt[3]{7}$

Step-by-step explanation:

The answer you are saying is correct if it was an equation

In inequalities the answer most of the times comes in ranges

The easiest way to find the range is by graphing the equation and finding the values of x for which the graph is above the x axis

There is a good graphing calculator app called desmos if u don't have one
