Answer: f(-2)=-6

Step-by-step explanation:

For this exercise it is important to remember the multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

You have the following function provided in the exercise, which represents the path traveled:

f(x) = 4x + 2

In order to find the value of f(-2) you can follow these steps:

1. You need to substitute x=-2 into the function, then:

f(-2) = 4(-2)+ 2

2. Finally you must evaluate. Then you get:

f(-2) =-8+ 2\\\\f(-2)=-6

Which best describes the range of the function f(x) = 2/3(6)x after it has been reflected over the x-axis?
AlladinOne [14]
The function is f(x) = [2/3] [6^x]


It is an exponential function whose range is all the positive values. This is, for any value of x that exponential function yields a value that is greater than 0. The graph never crosses the x-axis.


When you reflect the function over the x-axis, you flip the graph over x, and you can see that the range of the new fucntion iis all the negative values, this is all the real numbers less than zero.


Answer: all the real numbers less than zero.

An alloy is composed of nickel, zinc, and copper in a 7:2:9 ratio. How many kilograms of each metal is needed to make 3.8 kg of
Tamiku [17]
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x

7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21

Ni:   7x=7*0.21=1.47 ≈1.5 kg
Zn:  2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg

Check 1.5+0.4+1.9 =3.8 True
