Choose the function to match the graph.

the graph starts at the bottom of the y axis and rises along the y axis and curves to go through the point one comma negative three and continues to the right, leveling out around y equals negative two.

f(x) = log x − 3
f(x) = log x + 3
f(x) = log (x − 3)
f(x) = log (x + 3)

  (a)  f(x) = log x − 3

Step-by-step explanation:

The log function is zero for x=1. Here f(x) is -3 at x=1, so the log function has been shifted down 3 units.

  f(x) = log(x) -3

Here we need to remember general transformations. With that, we will see that the correct option is f(x) = log(x)− 3

Horizontal shift: For a general function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

If N is positive, the translation is to the left

If N is negative, the translation is to the right.

Vertical shift: For a general function f(x) a vertical shift of N units is written as:

g(x) = f(x) + N

If N is positive, the translation is upwards

If N is negative, the translation is downwards.

Now, we know that:

log(1) = 0

But if we look at our function, we can see that:

f(1) = -3

Then the correct option is the first one, because:

f(1) = log(1) - 3 = 0 - 3 = -3

Then we can see that this is a translation down of 3 units of the parent function log(x).

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

10 b/c 5*2 =10
