Answer:


Step-by-step explanation:
Given
The piece wise function
Solving (a): f(0)
To solve for f(0), we make use of:

Because: the inequality
satisfies x = 0
i.e: 
So, we have:



Solving (b): f(6)
To solve for f(6), we make use of:

Because: the inequality
satisfies x = 6
i.e: 
So, we have:

Answer:
(20 - 24)/6
Step-by-step explanation:
We have the algebraic expression
6(x + 4)= 20
We expand the brackets
6x + 24 = 20
Collect like terms
6x = 20 - 24
x = (20 - 24)/6
A correct solution to the expression is
(20 - 24)/6
There is no solution to this
