The most appropriate choice for function can be given by

qop(3) =  \sqrt{15}+1

poq(3) =  2\sqrt{3} + 10

What is function?

A function from A to B is a rule that maps to each element of A a unique element of B.

A is called the domain of the function and B is called the co domain of the function.

We can do addition, subtraction, multiplication, division and composition on functions.

Let f and g be two functions

fog(x) = f(g(x)) and gof(x) = g(f(x))

This is known as composition of function.

Here,

p(x) = x^2 + 6\\q(x) = \sqrt{x} +1

qop(x) = q(p(x))

          =q(x^2+6)

          = \sqrt{x^2+6}+1

qop(3) = \sqrt{3^2+6}+1

          = \sqrt{15}+1

poq(x) = p(q(x))

          = p(\sqrt{x}+1)

          = (\sqrt{x}+1)^2+6

          = x + 1 + 2\sqrt{x} + 6

          = x + 2\sqrt{x} +7

poq(3) = 3 + 2\sqrt{3}  +7

               2\sqrt{3} + 10

               2\sqrt{3} + 10

-4(5+n) = -12 need help​
user100 [1]

First, simplify out the brackets:

-20 - 4n = -12

Then, combine like terms by moving the -20 to the other side

-4n = -12 + 20

-4n = 8

Divide by -4 on both sides to isolate the n

n = 8/-4

n = -2
