The translation is down 5 because if you simplify or solve the second f(x), it would be x^2 - 5. I hope this helps :)

F(x) = x + 2 g(x) = x – 4 (f g)(x) =

Answer:

x² - 2x - 8

Step-by-step explanation:

The notation (f·g)(x) means to multiply the two functions. Use the distributive property to simplify.

(f·g)(x) = (x+2)(x-4) = x² + 2x - 4x - 8 = x² - 2x - 8

.......... is the slope zero

Eddi Din [679]

Answer:

Step-by-step explanation:

OK... You have to use this formula: Y2 - Y1

X2 - X1

-2 represents X1
7 represents Y1
2 represents X2
-5 represents Y2

Y2 - Y1

X2 - X1

-5 - 7

2 - - 2

-12

-2

Simplify by dividing both -12 & -2 by 2: -6

-1

It's either -6 or it's just -6 by itself... Really sorry if I'm wrong...

-1

PLEASE HELP!!!!!! What signals you that factoring by grouping is the best method to use when factoring a problem? How would you

ElenaW [278]

Normally when there is similar terms and when you have to figure out if it is factorable or prime you must first begin factoring it and if it does not work it is prime.
Hope this helps, ask me if you have any questions.

Can someone please clearly and correctly work out Q19? Would appreciate it a lot! :)

$x^{2} +10x+30$
I always start by moving the last term to the other side
$x^{2} +10x=-30$
To complete the square you take term 'b' , divide it by 2 then square it
$( \frac{10}{2} )^2$ = 25
We have to add 25 to what we have and what you do to one side you have to do to the other
$x^{2} +10x+25=-30+25$
$x^{2} +10x+25=-5$
Now we factor what is on the left side of the equation
$(x+5)^2=-5$
The last step is to move our right side of the equation back over
$(x+5)^2+5$ - which is your answer :)))
