If f(x) = 2x+7 and g(x) = -3x+5, what is f(g(1))?

Murrr4er [49]

Answer:

$f(g(1))=11$

Step-by-step explanation:

So we have the two functions:

$f(x)=2x+7\text{ and } g(x)=-3x+5$

And we want to find f(g(1)).

So, let's find g(1) first:

$g(x)=-3x+5$

Substitute 1 for x:

$g(1)=-3(1)+5$

Simplify:

$g(1)=-3+5$

Add:

$g(1)=2$

So:

$f(g(1))=f(2)$

Now, substitute 2 for x in f(x):

$f(x)=2x+7\\f(2)=2(2)+7$

Multiply:

$f(2)=4+7$

Add:

$f(2)=11$

So:

$f(g(1))=11$

<h3><u>Part A</u></h3>

$\sf \rightarrow y^2 - 3y - 4y +12$

factor the common term 'y' and '-4'

$\sf \rightarrow y(y - 3) - 4(y - 3)$

collect into groups

$\sf \rightarrow (y- 4)(y - 3)$

<h3><u>Part B</u></h3>

$\sf \rightarrow 9x^2 - 12x + 4$

middle term split

$\sf \rightarrow 9x^2 - 6x - 6x+ 4$

factor the common term '3x' and '-2'

$\sf \rightarrow 3x(3x - 2) -2( 3x-2)$

collect into groups

$\sf \rightarrow (3x -2)( 3x-2)$

simplify the following

$\sf \rightarrow (3x -2)^2$
