Evaluate \(\int^2_1(x^2 – 4x)dx\)
- \(\frac{11}{3}\)
- \(\frac{3}{11}\)
- \(-\frac{3}{11}\)
-
\(-\frac{11}{3}\)
The correct answer is: D
Explanation
\(\int^2_1(x^2 - 4x)dx\)\((\frac{x^3}{3} - \frac{4x^2}{2})\)
substituting integrate values
\([\frac{8}{3} - \frac{4 \times 4}{2}] - [\frac{1}{2} - 2]\)
= \(-\frac{11}{3}\)
