what is the range of the function f(x) = 3/4 |x|-3 A, all real numbers B. all real numbers less than or equal to 3 C. all real numbers less than or equal to –3 D. all real numbers greater than or equal to –3

Respuesta :

This is an absolute value function.

Were it not for that "-3" in     f(x) = 3/4 |x|-3, the vertex of the graph would be on the x-axis.

But that "-3" causes a downward vertical translation of 3 units.

Thus, the smallest possible y value is -3; there is no limit on y otherwise.

Range is [-3, infinity] 

The range of the function f(x) = 3/4 |x|-3 is [-3, [tex]\infty[/tex]) and this can be determined by using the graph of the given function.

Given :

Function  -- f(x) = 3/4|x| - 3

The steps can be used in order to determine the range of the function:

Step 1 - Write the given function.

f(x) = 3/4|x| - 3

Step 2 - Draw the graph of (y = x).

Step 3 - Now, take the mirror image of the graph obtained in the above step. So, the graph obtained is the graph of (y = |x|).

Step 4 - Now, multiply the y-axis by 3/4. So, the graph obtained is the graph of (y = 3/4|x|).

Step 5 - Now, translate the graph obtained in the above step in the downward direction by a factor of 3. So, the graph obtained is the graph of (y = 3/4|x| - 3).

Step 6 - From the graph obtained in the above step, it can be concluded that the range of the function is [-3, [tex]\infty[/tex]).

Therefore, the correct option is D).
