For this question, we have a graph and we are asked to figure out multiple parts.
00:05
The first part of the question asks us, what is f of negative 1? so wherever we, if we have the function f of x, right, we just have to replace x with negative 1.
00:16
So when x is negative 1, right, what is y? what is f of x? so that's right here, we see that y is negative 1.
00:26
Right, we have a negative 1 here.
00:28
So we have that this is equivalent to negative 1.
00:31
For part b of the question, what is f of zero? so when x is zero, right? we have what is y? why is also zero? for part c of the question, it asks us, when is f of x 3? so remember f of x is just y, right? so when y equals three, we have two values of x.
00:51
So we have a value of one and we also have a value of negative three, right? so x can equal negative three or one.
00:59
And then y will equal three.

The last part of the question asks us for the domain and range...
