4-3=1
Step-by-step explanation:
We need to find the value of the function at the indicated value.

Indicated values are : f(-7), f(0), f(6), f(7)
To find f(-7), put x = -7 in the given function

To find f(0), put x = 0 in the given function

To find f(6), put x = 6 in the given function

To find f(7), put x = 7 in the given function

Hence, this is the required solution.
