Enter g(x) in terms of f(x) after performing the given transformation of the graph of f(x). Translate the graph of f(x) to the left 4 units.

Given:

The graph of f(x) translated to the left 4 units.

To find:

The g(x) in terms of f(x) after performing the given transformation of the graph of f(x).

Solution:

The translation is defined as

               .... (1)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

Since graph of f(x) translated to the left 4 units, therefore, the value of a is 4 and value of b is 0.

Put a=4 and b=0 in (1).

Therefore, the required function is .

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
