Answer:
c) (-4,0), (4,0)
Step-by-step explanation:
In order to find all of the x-intercepts of the function using the table, you have to know the condition to calculate intercepts with the x-axis.
The condition is that there is an intercept with the x-asis when f(x) = 0
So, you have to find the points where f(x)=0 in the table
There are only two values of f(x) = 0 in the table, so there are two x-intercepts
The point x= -4 and f(x) = 0 and the point x=4 and f(x) = 0
You can write them as ordered pairs of the form ( x,f(x) ) :
(-4, 0) and (4,0)
