Sketch the graph of the function f(x) = -(x-4)^3 by indicating how a more basic function has been shifted, reflected, stretched,

irina [24]

Step-by-step explanation:

In the attached images we can see the rigid transformation of the function $f(x) =x^{3}$

1. The basic graph $f(x) =x^{3}$

2. The reflected graph $f(x) = -x^{3}$

3. The displaced graph $f(x) = -(x-4)^{3}$

Reflection: In the expression $f(x) = -(x-4)^{3}$ , the sign - before the parenthesis indicates that the function is reflected in the x axis, for this case the function is even, this means that -f(x) = f(-x) , then the reflection on the x axis is equal to the reflection on the y axis.

Displacement: We observe the term (x-4) of the function $f(x) = -(x-4)^{3}$ and analyze the value -4, where, the sign - indicates displacement to the right and the value 4 indicates the amount that the graph shifted .

What is the solution of the system? Use substitution. y = 6x + 2 3y - 18x = 12

kicyunya [14]

3(6x+2)-18x=12 (y=6x+2, so you plug in 6x+2 into the y in 3y-18x=12)
18x+6-18x=12 (Then you distribute the 3 to the 6x and to the 2)
6=12 (Combine like terms 18x-18x)

There is no solution. Hope this helps and makes sense.

The goals against average (A) for a professional hockey goalie is determined using the formula A = 60 a equals 60 left-parenthes

Marina CMI [18]

Answer:

Option 1 - $\frac{At}{60}=g$

Step-by-step explanation:

Given : The goals against average (A) for a professional hockey goalie is determined using the formula $A=60(\frac{g}{t} )$ . In the formula, g represents the number of goals scored against the goalie and t represents the time played, in minutes.
