Add/Subtract, simplified:

Picture below is simplified / evaluated

Step-by-step explanation for the domain:

Find the domain by finding where the expression is defined.

Interval Notation:

(−∞,0)∪(0,7)∪(7,∞)

Set-Builder Notation:

{x|x≠0,7}

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
