f'(x) 3x^2 - 5x+ 3

f(x) = integral f'(x).

==> f(x) = intg (3x^2 - 5x + 3) dx

= intg (3x^2)dx - intg (5x) dx + intg 3 dx

= 3x^3/3 - 5x^2 /2 + 3x + C

**==> f(x) = x^3 - (5/2)x^2 + 3x + C**

f'(x) 3x^2 - 5x+ 3

f(x) = integral f'(x).

==> f(x) = intg (3x^2 - 5x + 3) dx

= intg (3x^2)dx - intg (5x) dx + intg 3 dx

= 3x^3/3 - 5x^2 /2 + 3x + C

**==> f(x) = x^3 - (5/2)x^2 + 3x + C**
