Answer:

The answer is option 1.

Step-by-step explanation:

Firstly, you have to elaborate the expression :

{x}^{2}  + 10x + 21

=  {x}^{2}  + 3x + 7x + 21

Next you have to take out the common factors and factorize it :

{x}^{2}  + 3x + 7x + 21

= x(x + 3)  +  7(x + 3)

= (x + 7)(x + 3)

If f(x)=x+4 and g(x)=x^2-1, what is g(f(x))?
pickupchik [31]

g(f(x)) means plug in f(x) for every "x" in g(x).

g(f(x))=(x+4)^2-1=x^2+8x+16-1=x^2+8x+15

answer: x^2+8x+15

Could I have some help please

Since AB=AD, the triangle on the left is isosceles and has two 35 degree angles.  Since the sum of all the interior angles is 180 deg, 

x = 180 deg - 2(35 deg) = 110 deg (answer)

Answer:

\boxed{f(6) = 34}

Step-by-step explanation:

Composition of functions occurs when we have two functions normally written similar or exactly like f(x) & g(x) - you can have any coefficients to the (x), but the most commonly seen are f(x) and g(x). They are written as either f(g(x)) or (f o g)(x). Because our composition is written as (f \circ g)(2), we are replacing the x values in the g(x) function with 2 and simplifying the expression.

g(2) = 3(2)

g(2) = 6

Now, because we are composing the functions, this value we have solved for now replaces the x-values in the f(x) function. So, f(x) becomes f(6), and we use the same manner as above to simplify.

f(6) = (6)^2-2

f(6) = 36-2

f(6) = 34

Therefore, when we compose the functions, our final answer is \bold{f(6) = 34}.
