Question

If f(x)= 3x³+1-x,find (9x+1).

Answer 1

Answer:

10x

Step-by-step explanation:

If f(x) =3x³+1-x so finding (9x+1)..

9(x)+1

9+1(x)

10(x)

10 x is right answer because there is no f(x) term in this question

If the question is (9(fx)+1) then sol..

(9(3x³+1-x)+1)

(27x³+9-x(+1))

36x³-x(+1)

(36x²+1)

37x² is the right answer
