Find (f • g)(2) f(x)= 6x g(x)= 2x + 2 (f • g)(2)=

Mathematics
1 answer:
brilliants [131]3 years ago
7 0

Answer:

Step-by-step explanation:

Another way to state the composition of functions is, in this case, f(g(2)).  Which means we will evaluate the g function at an x value of 2, then take that solution and sub it into the f function for x.

g(2) = 2(2) + 2 and

g(2) = 6.  Now take that and sub it into f for x:

f(6) = 6(6) and

f(6) = 36

f(g(2)) = 36

Which would be used to solve this equation? Check all that apply.
puteri [66]

Answer:

multiplying both-side of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation:

To solve the equation p/3 = 12, we will follow the steps below;

first multiply 3 to both-side of the equation, that is:

p/3 × 3 = 12 × 3

On the left-hand side of the equation, 3 at the numerator will cancel-out 3 at the denominator, leaving us with just p while on the right-hand side of the equation 12 will be multiplied by 3

p= 36

To check the correctness of the equation, we can substitute p = 36 back into the equation and then check, that is;

p/3 = 12

36/3 = 12

This implies p = 36 is correct

eimsori [14]

Answer:

x=65/n where x is 1 book and n the number of books

Step-by-step explanation:

If n is the number of books, lets say 1 book is "x", then

nx=65

x=65/n

for example

n=1    then x=65

n=2 then x=65/2

n=3 then x=65/3
