Step-by-step explanation:

From your question, what you need is the explanation;

Given that  is a factor of p(x)

Required: Simplify

Group the expression above

-------- Expression 1

The expression can be expanded using difference of two squares;

By comparison, Expression 1 can be rewritten as

Open both brackets

Expand the above expression

Remove bracket

Hence,

If

 is a factor of p(x)

Then

is a factor of p(x)

d. is the correct answer

step-by-step explanation:

(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)
