The graph of function f is shown on the coordinate plane. Graph the line representing function g, if g is defined as shown below

Aleonysh [2.5K]

Answer:

$g(x)=x-1$

Step-by-step explanation:

Any problem of this kind should first be approached by solving the initial function.

This question is based on curve translation on x-axis. But, there can be questions asked on translation in both axes, rotation of curve about origin, or both combined.

Initial function f(x) is a straight line from picture.

Common equation of straight line is

$y=mx+c$

m= slope of the line

c= y-intercept

Slope of the line:

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

Let those points on graph be A(3,0) and B(0,-6)

Therefore, slope of line AB, using formula is:

$m=\frac{0-(-6)}{3-0}$

m=2

And c=(-6)

And equation of line AB is:

$y=2x-6$

$f(x)=2x-6$

Now this line is translated backwards by 2 units, (x) becomes (x+2)

Let us consider a X, such that, $X=x+2$

$f(X)=2X-6$

$f(x+2)=2(x+2)-6$

$f(x+2)=2x+4-6$

$f(x+2)=2x-2$

Now, there is another function such that, $g(x)= \frac{1}{2} f(x+2)$

$g(x)= \frac{1}{2}(2x-2)$

$g(x)= x-1$ ; according to your question.

In the picture, they are asking for a function, $g(x)= \frac{-1}{2} f(x+2)$

Then, $g(x)= -x+1$ ; according to the picture.

Here, I have attached a file showing all the graphs for clear understanding.

Mckenzie bought 1.2 pounds of coffee for 11.82 what was cost of per pound

borishaifa [10]

first you divide 1.2 by its self because you need to get 1 pound. 1.2 / 1.2 = 1

now that you have one pound, you divide 11.82 by 1.2 = 9.85
