Question

If graph of a given function y = f(x) is as follows,
Then answer the following questions :
The range of a given function is

• A. [3 , 3]
• B. [4, 6]
• C. [1, 1]
• D. [0, 3]

Answer 1

The correct option is D [0, 3]

From the given fig,

the range will be the max point and min-points in the y axis of graph.

Range of $y=f\left(x\right)\in [3,-3]$

Now, from the given option,

[0,3] is the most surtasle subset from the Range.

$\therefore optionD=[0,3]$
