If f(x)=-x^2-1 and g(x)=x+5 then f(g(x)) =

sammy [17]

Answer:

The composition of f(g(x)) is:

$f(g(x)) = -x^2-10x-26$

Step-by-step explanation:

Given two functions are:

$f(x) = -x^2-1\\g(x) = x+5$

we have to find the composition of f and g which can also be written as: fog(x) or f(g(x))

The method to find the composition is that we will put the function g in place of x in function f

$f(g(x)) = -(x+5)^2-1\\=-(x^2+25+10x)-1\\=-x^2-25-10x-1\\=-x^2-10x-26$

Hence,

The composition of f(g(x)) is:

$f(g(x)) = -x^2-10x-26$

What is the completely factored form of t4 − 16?

Mashcka [7]

we know that

A difference of squares problem can be factored as follows:

$a^{2}-b^{2} =(a+b)(a-b)$

in this problem we have

$t^{4}-16$

Applying difference of squares

$t^{4}-16=(t^{2}-4)( t^{2}+4)$

the term

$(t^{2}-4)=(t+2)(t-2)$

substitute

$(t^{2}-4)( t^{2}+4)=(t+2)(t-2)( t^{2}+4)$

therefore

<u>the answer is</u>

$(t+2)(t-2)( t^{2}+4)$
