The figure shows the function p(x)=[x]. which statement about the function is not true?
a) p(0)=0
b) p(-4)=4
c) p(4)=-4
d) the domain of p(x) is all real numbers

The option that's not true is:

C) p(4) = -4

Because if you look at that graph, you can tell, p(4) = 4 not -4.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
