Given that f(x) = x2 − 4x − 3 and g(x) = the quantity of x plus three, over four , solve for f(g(x)) when x = 9. @Teddyiswatshecallsme

Question

teddyiswatshecallsme · Answer

:/ Sorry i can't help i havee no idea in functions....

anonymous · Answer

Below are two different functions, f(x) and g(x). What can be determined about their slopes?


f(x) Alex earns 1600 dollars in 400 hours.	
x
g(x)
1
−8
5
12
9
32


HOW ABOUT THIS ONE? @Teddyiswatshecallsme

$Given\;that\;f(x) = x^{2} − 4x − 3\;and\;g(x) = \dfrac{x+3}{4},\;find\;f(g(x))\;for\;x=9.$

You should not be struggling with this.  We're just evaluating functions.

g(9) = (9+3)/4 = 12/4 = 3
f(3) = 3^2 - 4(3) - 3 = 9 - 12 - 3 = -3-3 = -6

Is there a part of that you actually can't do?

anonymous · Answer

I did g(9)=9+3/3 
         g(9)=3
and then I plug in f(3)x^2-4x-3 
                           equaling out to  0... idk what I did wrong.

below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?


f(x) = x + 4
	
 (x)                  g(x)
−1                 8
1                    0
2                   −4


I also have a lot of trouble finding the y intercept when they give me a x and the g(x)
